(In reply to fatalnix from comment #6)

it's my understanding that adding the device to the bridge switches off the=
 NIC
offloading features automatically.

i'm getting 942Mb/sec and interestingly the dropped packets are limited to a
single txq, which changes between each test run:

dev.igb.0.iflib.txq3.r_drops: 188
dev.igb.0.iflib.txq2.r_drops: 130
dev.igb.0.iflib.txq1.r_drops: 69 <-- only one of these increments during ea=
ch
test=20
dev.igb.0.iflib.txq0.r_drops: 4636

--=20
