#16 setup fix for LNE100TX with LC82C168

[Mark Vytlacil]

Old LNE100TX would not see packets addressed to its MAC unless the setup frame was resent. It appears that
the card will not act appropriately on a setup frame while it is in the process of autonegotiation. The patch
delays transmitting the setup frame until do_pnic_nway() restarts RxTx.

Driver did not keep card in allmulti or promiscuous mode when explicitly set. Fix in do_pnic_nway().

Typo error in tulip_init_one() set CSR6 instead of 0xB8. Not much effect.

This patch against 1.1.8 makes my card work, but it may not be the best way.
