Fixes: - flow control - don't override user value on re-init - fix to make 1G optics work correctly - change to interrupt enabling - some bits were incorrect for certain hardware. - certain stats fixes, remove a duplicate increment of ierror, thanks to Scott Long for pointing these out. - shared code link interface changed, requiring some core code changes to accomodate this. - add an m_adj() to ETHER_ALIGN on the recieve side, this was requested by Mike Karels, thanks Mike. - Multicast code corrections also thanks to Mike Karels.
