This bug still exists, though now it is in mainline. I just bisected
to it with this config[1], unless, of course randconfig is still
making bad configs.
Errors out with:
drivers/built-in.o: In function `myri10ge_poll':
myri10ge.c:(.text+0xce259): undefined reference to `lro_receive_frags'
myri10ge.c:(.text+0xce37c): undefined reference to `lro_flush_all'
It bisects back to this with this:
sbh@shapeshifter /tmp/tester/linux-2.6 $ git-bisect bad
1e6e9342d41ff80ced0ad5dfcf084926700cdfc5 is first bad commit
