These new fields declare the number of MSI-X vectors that is
possible to allocate on the VF through PF configuration.
Value must be in range defined by min_dynamic_vf_msix_table_size

The driver should continue to query its MSI-X table th

Add do_mark_test(), which is to do_ecn_test() like do_drop_test() is to
do_red_test(): meant to test that actions on the RED mark qevent block are
offloaded, and executed on ECN-marked packets.

v3:
* Renamed pci_set_msix_vec_count to be pci_vf_set_msix_vec_count.
* Added VF msix_cap check to hide sysfs entry if device doesn't support msix.

Extend PCI sysfs interface with a new callback that allows configure
the number of MSI-X vectors for specific SR-IO VF. This is needed
to optimize the performance of newly bound devices by allocating
the number of vectors based on the administrator knowledge of targeted VM.
From: Leon Romanovsky
The number of MSI-X vectors is PCI property visible through lspci, that
field is read-only and configured by the device. The static assignment
of an amount of MSI-X vectors doesn't allow utilize the newly created
VF because it is not known to the device the future load and c

Some SR-IOV capable devices provide an ability to configure specific
number of MSI-X vectors on their VF prior driver is probed on that VF.
In order to make management easy, provide new read-only sysfs file that
returns a total number of possible to configure MSI-X vectors.

The RED "mark" qevent can be offloaded under the same exact conditions as
the RED "tail_drop" qevent. Therefore recognize its binding type in the

The corresponding hardware trigger, MLXSW_SP_SPAN_TRIGGER_ECN, is
