This speeds up link-up time on 5706 SerDes if the link partner does not autoneg, a rather common scenario in blade servers. Some blade servers use IPMI for keyboard input and it's important to minimize link disruptions. The speedup is achieved by shortening the timer to (HZ / 3) during the transient period right after initiating a SerDes autoneg. If autoneg does not complete, parallel detect can be done sooner. After the transient period is over, the timer goes back to its normal HZ interval. As suggested by Jeff Garzik, the timer initialization is moved to bnx2_init_board() from bnx2_open(). An eeprom bit is also added to allow default forced SerDes speed for even faster link-up time. Signed-off-by: Michael Chan <mchan@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>
