Bonding driver sending too-large packet to be2net ethernet interface (GSO)

Issue

• Where the kernel is passing a GSO packet with size 64k down to the hardware, but the hardware can't support it.

• This appears to be the same issue as https://bugs.launchpad.net/emulex/+bug/1078184 - the bonding driver isn't honoring the gso max packet/segment size requested from the underlying network interface.
