Hello,

I have the following problem with the new bce(4) driver on a 7.2-=20
PRERELEASE from a few days ago.
When I run tcpdump on the bce interface on the machine, all incoming =20
frames are shown as 2026 in size,
but on the sending machine tcpdump reports that it's sending frames of =20=

the correct size.
This looks very strange because I don't have enabled Jumbo Frames on =20
this bce interface , and it is still with it's default MTU of 1500 =20
bytes.
When I tried to capture the packets, they are zero padded to the 2026 =20=

frame size. The checksums are correct, so I suspect a driver bug?

P.S.: I experience this problem on several machines with bce =20
interfaces, and on all of them tcpdump sees all incoming frames with =20
length of 2026 bytes.

Regards,
Niki Denev
