New em driver breaks jumbo frames

2006-11-02 Thread Craig Boston
Don't have much time right now, but wanted to report that the new em
driver in -STABLE breaks jumbo frame support for me.  With it in the
kernel and this card:

em1: Intel(R) PRO/1000 Network Connection Version - 6.2.9 port 0xe8c0-0xe8ff 
mem 0xfe18-0xfe19 irq 18 at device 12.0 on pci2

I'm unable to send an ethernet frame bigger than 2034 bytes, no matter
what the mtu is set to.  No errors, no kernel messages, it just doesn't
go out.  tcpdump on both local and remote side show nothing at all.

Reverting to the previous driver fixed it.

Yes, this is the second report I've had, other came to me personally.
I'm looking into it.

There is already a PR about it.

Ah, thanks, guess I should have searched there first...
