| |
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.
