I realize this PR has been closed for over 6 months, but I'm seeing
similar symptoms in 6.2REL with my nve0 interface.
In looking at the current code in if_nve.c, it looks like things have
changed a little bit since the patch in this PR, but most of the patch
still exists. The major difference I see is that it now uses
sc->pending_txs to see if there are any pending packets instead of just
checking for it =3D=3D 0. Without knowing more about the hardware, would=
it
make more sense for the "pending_txs_start =3D sc->pending_txs;" line to
be *after* the driver is kicked by tweaking the interrupts?
For the specifics of my system:
6.2-RELEASE amd64
Motherboard: ASUS M2NPV-VM (integrated NVIDIA nForce=AE 430 built-in
Gigabit MAC)
=20
It looks like it is only having problems when passing lots of traffic.=20
Also, I do go through two switches at the moment, that will change when
I get home tonight.
