I compiled in the mbuf alignment patch in the arm32 if_ea.c and if_eb.c
and they compile. I'm currently doing speed tests to see if there is a
significant performance gain/lossage but i dont think so really.

just ran the test... no noticable change ... is it for your bcopy() is
only word aligned?

I get a 300 kb/sec :( for FTP and thats quite bad ... dunno why ... i'm
gonna check that out...

CYA
