2019-03-26ice: Put __ICE_PREPARED_FOR_RESET check in ice_prepare_for_resetBrett Creeley
Currently we check if the __ICE_PREPARED_FOR_RESET bit is set prior to calling ice_prepare_for_reset in ice_reset_subtask(), but we aren't checking that bit in ice_do_reset() before calling ice_prepare_for_reset(). This is not consistent and can cause issues if ice_prepare_for_reset() is called prior to ice_do_reset(). Fix this by checking if the __ICE_PREPARED_FOR_RESET bit is set internal to ice_prepare_for_reset().

2019-03-25ice: Prevent unintended multiple chain resetsDave Ertman
In the current implementation of ice_reset_subtask, if multiple reset types are set in the pf->state, the most intrusive one is meant to be performed only, but the bits requesting the other types are not being cleared. This would lead to another reset being performed the next time the service task is scheduled. Change the flow of ice_reset_subtask so that all reset request bits in pf->state are cleared, and we still perform the most intrusive of the resets requested.

2019-03-25ice: map Rx buffer pages with DMA attributesMaciej Fijalkowski
Provide DMA_ATTR_WEAK_ORDERING and DMA_ATTR_SKIP_CPU_SYNC attributes to the DMA API during the mapping operations on Rx side. With this change the non-x86 platforms will be able to sync only with what is being used (2k buffer) instead of entire page. This should yield a slight performance improvement. Furthermore, DMA unmap may destroy the changes that were made to the buffer by CPU when platform is not a x86 one. DMA_ATTR_SKIP_CPU_SYNC attribute usage fixes this issue. Also add a sync_single_for_device call during the Rx buffer assignment, to make sure that the cache lines are cleared before device attempting to write to the buffer.

2019-03-25ice: Limit the ice_add_rx_frag to frag additionMaciej Fijalkowski
Refactor ice_fetch_rx_buf and ice_add_rx_frag in a way that we have standalone functions that do either the skb construction or frag addition to previously constructed skb. The skb handling between rx_bufs is spread among various functions. The ice_get_rx_buf will retrieve the skb pointer from rx_buf and if it is a NULL pointer then we do the ice_construct_skb, otherwise we add a frag to the current skb via ice_add_rx_frag. Then, on the ice_put_rx_buf the skb pointer that belongs to rx_buf will be cleared. Moving further, if the current frame is not EOP frame we assign the current skb to the rx_buf that is pointed by updated next_to_clean indicator. What is more during the buffer reuse let's assign each member of ice_rx_buf individually so we avoid the unnecessary copy of skb. Last but not least, this logic split will allow us for better code reuse when adding a support for build_skb.

2019-03-25ice: Introduce bulk update for page countMaciej Fijalkowski
{get,put}_page are atomic operations which we use for page count handling. The current logic for refcount handling is that we increment it when passing a skb with the data from the first half of page up to netstack and recycle the second half of page. This operation protects us from losing a page since the network stack can decrement the refcount of page from skb. The performance can be gently improved by doing the bulk updates of refcount instead of doing it one by one. During the buffer initialization, maximize the page's refcount and don't allow the refcount to become less than two.

2019-03-25ice: Get rid of ice_pull_tailMaciej Fijalkowski
Instead of adding a frag and later when dealing with EOP frame accessing that frag in order to copy the headers onto linear part of skb, we can do this in ice_add_rx_frag in case where the data_len is still 0 and frame won't fit onto the linear part as a whole. Function comment of ice_pull_tail was a bit misleading because of mentioned optimizations that can be performed (drop a frag/maintaining accurate truesize of skb) - it seems that this part of logic was dropped and the comment was not updated to reflect this change.

This patch fixes issue reclaiming VF resources back to the pool after reset - Since we only allocate HW vector for all VFs and track together with resources allocation for PF with ice_search_res, we need to free VFs resources separately, using first VF vector index to traverse the list. Otherwise tracker starts from the last assigned vectors list and causes maximum supported number of HW vectors, 1024 to be exhausted, depending on the number of VFs enabled, which causes a lot of unwanted issues, and failed to reassign vectors for VFs.

Michal adds support for the pruning enable flag to avoid seeing broadcast packets on different VLANs. Akeem fixes an issue with VF queues being disabled and the VF netdev network carrier being lost after reset. Fixed an issue issue when doing PFR and CORER resets, where all VF VSIs need to be reset and rebuilt with the main VSIs before replaying all VSIs. Resolved an issue to properly initialize VFs in the guest OS via PCI passthrough. Bruce adds a local variable to avoid unnecessary de-references throughout ice_probe(). Brett cleans up the code a bit by removing the need for a local variable and re-designs the loop to simply return when get a successful result. Cleans up the code to replace loop calls with a predefined macro to make the code more consistent. Updated the driver to ensure ITR granularity is always 2 usecs. Refactors the calculation of VSIs per PF into a general function that can calculate per PF allocations for not just VSIs but across multiple resource types. Improve the driver performance of the driver when using the default settings by determining the ring size and the number of descriptors for transmit and receive based on a calculation with the PAGE_SIZE, ICE_MAX_NUM_DESC, and ICE_REQ_DESC_MULTIPLE.

Instead of assuming 4K pages, determine the ring size and the number of descriptors for Tx and Rx based on a calculation using the PAGE_SIZE, ICE_MAX_NUM_DESC, and ICE_REQ_DESC_MULTIPLE.

2019-03-19ice: remove redundant variable and if conditionBrett Creeley
In ice_pf_rxq_wait we are using an unnecessary local variable and also we are checking if the timeout time was reached after the loop. Get rid of the local variable and return 0 right when we get a successful result. This makes it so we can return -ETIMEDOUT if we ever exit the loop because we know the timeout time has been hit.

2019-03-19ice: Fix issue with VF reset and multiple VFs support on PFsAkeem G Abodunrin
This patch fixes issues with VF queues being disabled, and VF netdev network carrier being lost after reset. Basically, we need to check if VF is enabled, and queue configured in reset_all_vfs flow, and disable/enable those queues appropriately whenever the function is called after Global/CORER/PFR reset/rebuild/replay.

2019-03-19ice: Fix broadcast traffic in port VLAN modeMichal Swiatkowski
Set egress (Rx) pruning enable flag for VF VSI in VSI ctxt to enable prune action. To avoid seeing broadcast packet in different VLAN, pruning enable flag in VSI ctxt should be set. Write new functions (fill VSI ctx) to not repeat send ctxt code.
