2016-11-30qede: Add support for XDP_TXMintz, Yuval
Add support for forwarding via XDP. Once the eBPF is attached, driver would allocate & configure a designated transmission queue meant solely for forwarding packets. Said queue would share the receive-queue's interrupt line, and would have it's own Tx statistics. Infrastructure changes required for this [spread-out through the code]: - Determine the DMA direction of the receive buffers based on the presence of the eBPF program. - Turn the sw Tx ring into a union, as regular/XDP queues have different needs for releasing resources after completion [regular requires the SKB, XDP requires the transmitted page].

2016-11-30qede: Add basic XDP supportMintz, Yuval
Add support for the ndo_xdp callback. This patch would support XDP_PASS, XDP_DROP and XDP_ABORTED commands. This also adds a per Rx queue statistic which counts number of packets which didn't reach the stack [due to XDP]. Signed-off-by: Yuval Mintz <Yuval.Mintz@cavium.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2016-11-30qede: Better utilize the qede_[rt]x_queueMintz, Yuval
Improve the cacheline usage of both queues by reordering - This reduces the cachelines required for egress datapath processing from 3 to 2 and those required by ingress datapath processing by 2. It also changes a couple of datapath related functions that currently require either the fastpath or the qede_dev, changing them to be based on the tx/rx queue instead.

2016-11-30qede: Revise state locking schemeMintz, Yuval
As qede utilizes an internal-reload sequence as result of various configuration changes, the netif state wouldn't always accurately describe the status of the configuration. To compensate, we're storing an internal state of the device, which should only be accessed under the qede_lock. This patch fixes and improves several state/lock interactions: - The internal state should only be checked while locked. - While holding lock, it's preferable to check state rather than the netdevice's state. - The reload sequence is not 'atomic' - unload and subsequent load are not in the same critical section. This also add the 'locked' variant for the reload, which would later be used by XDP - useful in the case where the correct sequence is 'lock, check state and re-configure if good', instead of allowing the reload itself to make the decision regarding the configurability of the device.

2016-11-30qede: Refactor statistics gatheringMintz, Yuval
Refactor logic for gathering statistics into a per-queue function. This improves readability of the driver statistics' flows. In addition, this would be required by the XDP forwarding queues [as we'll need the Txq statistics gathering methods for those as well].

2016-10-31qed*: Management firmware - notifications and defaultsSudarsana Kalluru
Management firmware is interested in various tidbits about the driver - including the driver state & several configuration related fields [MTU, primtary MAC, etc.]. This adds the necessray logic to update MFW with such configurations, some of which are passed directly via qed while for others APIs are provide so that qede would be able to later configure if needed. This also introduces a new default configuration for MTU which would replace the default inherited by being an ethernet device.

2016-10-31qede: Fix statistics' strings for Tx/Rx queuesMintz, Yuval
When an interface is configured to use Tx/Rx-only queues, the length of the statistics would be shortened to accomodate only the statistics required per-each queue, and the values would be provided accordingly. However, the strings provided would still contain both Tx and Rx strings for each one of the queues [regardless of its configuration], which might lead to out-of-bound access when filling the buffers as well as incorrect statistics presented.

2016-07-01qede: Add support for handling IP fragmented packets.Manish Chopra
When handling IP fragmented packets with csum in their transport header, the csum isn't changed as part of the fragmentation. As a result, the packet containing the transport headers would have the correct csum of the original packet, but one that mismatches the actual packet that passes on the wire. As a result, on receive path HW would give an indication that the packet has incorrect csum, which would cause qede to discard the incoming packet. Since HW also delivers a notification of IP fragments, change driver behavior to pass such incoming packets to stack and let it make the decision whether it needs to be dropped.

2016-04-25qed*: Conditions for changing linkYuval Mintz
There's some inconsistency in current logic determining whether the link settings of a given interface can be changed; I.e., in all modes other than the so-called `deault' mode the interfaces are forbidden from changing the configuration - but even this rule is not applied to all user APIs that may change the configuration. Instead, let the core-module [qed] decide whether an interface can change the configuration by supporting a new API function. We also revise the current rule, allowing all interfaces to change their configurations while laying the infrastructure for future modes where an interface would be blocked from making such a configuration.
