 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.
