- Change tc_mapping field to assign 64 queues instead of 16 to the PF's VSI;
add comments to describe how this is done.

- Set hash lut size to 512 when setting filter control; the lut size defaults
to 128 if this isn't set.

Fix ixl(4) compilation with PCI_IOV pre-r266974

stable/10 doesn't have the if_getdrvflags(9) KPI. Reference the field in the
structure directly if the __FreeBSD_version is < 1100022, so the driver can
be built with PCI_IOV support on stable/10, without backporting all of
r266974 (which requires additional changes due to projects/ifnet, etc)
