Subject[patch 2.4.28-rc3] 3c59x: reload EEPROM values at rmmod for needy cards
Enable reload of EEPROM values in reset at rmmod for cards that need
it, similar to old EEPROM_NORESET flag but in reverse.

Signed-off-by: John W. Linville <linville@tuxdriver.com>
---
3c905 cards need an additional bit unmasked in the reset at rmmod or
else they don't get reinitialized properly when the driver is reloaded.

This is a repost -- the previous patch appears to have been lost
in the shuffle. This is the combination of the two patches posted
previously regarding EEPROM_NORESET.
