[Bug 560210] [NEW] Can't enable jumbo frames on Intel 82573V (e1000e)

[Holger Mauermann]

Public bug reported:

Enabling jumbo frames on a Intel 82573V NIC fails in Lucid:

# ifconfig eth2 mtu 9000
SIOCSIFMTU: Invalid argument

This worked in Jaunty (not sure about Karmic - I skipped this on this
computer).

(Jaunty)
# modinfo e1000e | grep ^version
version:        0.3.3.3-k6
# uname -a
Linux cx1 2.6.28-18-server #59-Ubuntu SMP Thu Jan 28 02:25:03 UTC 2010 x86_64 GNU/Linux

(Lucid)
# modinfo e1000e | grep ^version
version:        1.0.2-k2
# uname -a

# lspci | grep Ethernet

11:00.0 Ethernet controller: 3Com Corporation 3c905C-TX/TX-M [Tornado] (rev 6c)

Jumbo frames with 82574L and 82573L are working without problems, only
the 82573V gives above error message.
