Nitpick: if you don't have firmware, don't set fw_version at all.
Ben.
Then ethtool prints empty string as firmware version, I think "N/A" is more intuitive.
Can will remove, if it is preferred way.
But I have a question to networking guru's:
This chip have FRAME_SIZE limited to 1514, including eth header.
So, for 802.1Q vlan packets mtu must be set to 1496.
For now we handle this from userspace, but I think this is wrong in general
- handling hardware bugs and limitations is kernels job.
Can driver somehow limit mtu for slave vlan devices to 1496, but still use 1500
for plain ethernet?
->ndo_change_mtu is called for master device only, not for it's slaves.
(and sorry for my russian english, just in case)
