[src/trunk]: src/sys/dev/pci/ixgbe Add support ALLMULTI on ixv(4):
details: https://anonhg.NetBSD.org/src/rev/e38ef9dfc25b
branches: trunk
changeset: 459450:e38ef9dfc25b

description:
Add support ALLMULTI on ixv(4):
- Negotiate API version up to 1.3.
- On linux's PF driver implementation, the PF replies VF's XCAST_MODE_ALLMULTI
message not with NACK but with ACK even if the virtual function is NOT
marked "trust" and act as XCAST_MODE_"MULTI". If ixv(4) simply check the
return vaule of update_xcast_mode(XCAST_MODE_ALLMULTI), SIOCSADDMULTI
success and the user may have trouble with some addresses. Fortunately,
the Linux's PF driver's "ACK" message has not XCAST_MODE_"ALL"MULTI but
XCAST_MODE_MULTI, so we can check this state by checking if the send
message's argument and the reply message's argument are different.
- Noy yet for PROMISC.
