share/man/man4/ixv.4 1.3, 1.6-1.7
- Fix a problem that the RX path stalled when the mbuf cluster is
exhausted.
- Modify some parameters to reduce packet dropping. See also the
manual's OPTIONS section for the detail.
- ixv(4): The max number of queue(pair) is not 7 but 8. Correctly
reset the hardware.
- Add "TX " to "Queue No Descriptor Available" evcnt(9) name to make
it more understandable.
- Fix a bug that some advertise speeds can't be set with
hw.ixgN.advertise_speed if both 2.5G and 5G are set. Fix the error
message, too.
- Fix typo in comment or debug message.
