The implementation was a bit krusty. The 10s rtl8169_phy_timer timer has been (was ?) required with older 8169 for adequate phy operation when full gigabit is advertised in autonegotiated mode. The timer does nothing if the link is up. Otherwise it keeps resetting the phy until things improve. - the device private data field phy_1000_ctrl_reg was used to schedule the timer. Avoid it and save a few bytes. - rtl8169_set_settings pending timer is disabled before changing the link settings as rtl8169_phy_timer is not always needed (see the removed test in rtl8169_phy_timer). - rtl8169_set_speed bail out early on failure. - rtl8169_open Calling rtl8169_request_timer duplicates -> rtl8169_init_phy -> rtl8169_set_speed -> mod_timer NB : the latter does not care about RTL_GIGA_MAC_VER_01. - rtl8169_request_timer : unused yet. Removed. - rtl8169_delete_timer : useless. Bloat. Removed. Side effect : the timer may kick in if the TBI is enabled. I do not know if the TBI has ever been used inr eal life.
