I'm using a 82599 Nic for project.
And I want to use VM tx WRR mode.
So I setting RTTDCS register to 0x00000002| 0x00400000 ( setting VMPAC bit
and BDPM bit in RTTDCS).
but when I set RTTDCS.VMPAC bit. Nic can't send packet.
And kernel print 'tx unit Hang' in ixgbe message.
when RTTDCS.VMPAC bit is not set, Nic operating well.
system setting is like this.
driver : Ixgbe-3.3.8 driver
kernel : 2.6.35.6-45.fc14.x86_64
ram : 12GB
thanks,
Park.
