2019-05-05nfp: flower: add qos offload install and remove functionality.Pieter Jansen van Vuuren
Add install and remove offload functionality for qos offloads. We first check that a police filter can be implemented by the VF rate limiting feature in hw, then we install the filter via the qos infrastructure. Finally we implement the mechanism for removing these types of filters.

Jesse updated the driver to make more functions consistent in their use of a local variable for vsi->back. Updates the driver to use bit fields when possible to avoid wasting lots of storage space to store single bit values. Optimized the driver to be more memory efficient by moving structure members around that are not in are hot path. Michal updates the driver to disable the VF if malicious device driver (MDD) event is detected by the hardware. Adds checks to validate the messages coming from the VF driver. Tightens up the sniffing of the driver so that transmit traffic so that VF's cannot see what is on other VSIs. Tony fixed the driver so that receive stripping state won't change every time transmit insertion is changed. Cleanup the __always_unused attribute, now that the variable is being used. Fixed the function which evaluates setting of features to ensure that can evaluate and set multiple features in a single function call. Akeem fixes the driver so that we do not attempt to remove a VLAN filter that does not exist. Adds support for adding a ethertype based filter rule on VSI and describe it in a very long run-on sentence. :-) Bruce cleans up static analysis warnings by removing a local variable initialization that is not needed. Brett makes the allocate/deallocate more consistent in all the driver flows for VSI q_vectors. In addition, makes setting/getting coalesce settings more consistent throughout the driver. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

Sergey adds a check for the number of vectors against the number of MSIx vectors to ensure one does not exceed the other. Martyna adds additional input validation on VF messages handled by the PF. Fixed potential memory leaks in the driver where the error paths were not freeing allocated memory.

2019-05-04i40e: Use struct_size() in kzalloc()Gustavo A. R. Silva
One of the more common cases of allocation size calculations is finding the size of a structure that has a zero-sized array at the end, along with memory for some number of elements for that array. For example: struct foo { int stuff; struct boo entry[]; }; size = sizeof(struct foo) + count * sizeof(struct boo); instance = kzalloc(size, GFP_KERNEL) Instead of leaving these open-coded and prone to type mistakes, we can now use the new struct_size() helper: instance = kzalloc(struct_size(instance, entry, count), GFP_KERNEL) Notice that, in this case, variable size is not necessary, hence it is removed.

2019-05-04ice: Disable sniffing VF traffic on PFMichal Swiatkowski
Delete code that add default Tx rule on PF. With this rule PF can see Tx VF traffic that should go outside. For traffic from VF to another VF default Tx rule on PF doesn't apply because of lower priority than VF mac rule. With this change on PF in promisc mode we can see only Rx traffic that doesn't match any other rule (mac etc.). We can't see Tx traffic from other VSI.

2019-05-04ice: Use more efficient structuresJesse Brandeburg
Move a bunch of members around to make more efficient use of memory, eliminating holes where possible. None of these members are hot path so cache line alignment is not very important here.

2019-05-04ice: Use bitfields where possibleJesse Brandeburg
The driver was converted to not use bool, but it was neglected that the bools should have been converted to bit fields as bit fields in software structures are ok, as long as they use the correct kinds of unsigned types. This avoids wasting lots of storage space to store single bit values. One of the change hunks moves a variable lport out of a group of "combinable" bit fields because all bits of the u8 lport are valid and the variable can be packed in the struct in struct holes.

2019-05-04ice: Add function to program ethertype based filter rule on VSIsAkeem G Abodunrin
This patch adds function to program VSI with ethertype based filter rule, so that all flow control frames would be disallowed from being transmitted to the client, in order to prevent malicious VSI, especially VF from sending out PAUSE or PFC frames, and then control other VSIs traffic.

2019-05-04ice: Separate if conditions for ice_set_features()Tony Nguyen
Set features can have multiple features turned on|off in a single call. Grouping these all in an if/else means after one condition is met, other conditions/features will not be evaluated. Break the if/else statements by feature to ensure all features will be handled properly.

2019-05-04ice: Suppress false-positive style issues reported by static analyzerBruce Allan
A recent version of cppcheck falsely reports- Variable ip.hdr is assigned a value that is never used. ip is a union so the pointer ip.hdr is actually used when referenced as ip.v4 and ip.v6. Silence these false reports when using cppcheck with the --inline-suppr command-line option.

2019-05-04ice: Refactor getting/setting coalesceBrett Creeley
Currently if the driver has an uneven amount of Rx/Tx queues setting the coalesce settings through ethtool will result in an error. This is happening because in the setting coalesce flow we are reporting an error if either Rx or Tx fails. Also, the flow for setting/getting per_q_coalesce and setting/getting coalesce settings for the entire device is different. Fix these issues by adding one function, ice_set_q_coalesce(), and another, ice_get_q_coalesce(), that both getting/setting per_q and entire device coalesce can use. This makes handling the error cases generic between the two flows and simplifies __ice_set_coalesce() and __ice_get_coalesce(). Also, add a header comment to __ice_set_coalesce().

2019-05-04ice: Always free/allocate q_vectorsBrett Creeley
Currently when probing/removing the driver we allocate/deallocate each vsi->q_vectors array in ice_vsi_alloc_arrays() and ice_vsi_free_arrays() respectively. However, we don't do this during the reset and VSI rebuild flow. This is inconsistent and unnecessary to have a difference between the two flows. This patch makes the change to always allocate/deallocate the vsi->q_vectors array regardless of the driver flow we are in. Also, update the comment for ice_vsi_free_arrays() to be more descriptive.
