The main MAC config registers like: RCTRL/TCTRL, MRBLR, MAXFRM, RXIC/TXIC, most fields of MACCFG1/2, should not be changed on-the-fly, but at least after stopping the DMA and disabling the Rx/Tx blocks and, for increased reliability, after a MAC soft reset. Impelement a complete MAC soft reset and reconfig procedure following the latest HW advisories - gfar_mac_reset() - to replace gfar_mac_init() and (the confusing) init_registers() functions. Factor out separate config functions for RCTRL and TCTRL, insure programming order of the relevant config regs after MAC soft reset. Split gfar_hw_init() into gfar_mac_reset() and the remaining global regs that don't need to be reconfigured after MAC soft reset (FIFOCFG, ATTRELI, HW counters a.s.o). As gfar_hw_init() now makes all the register writes @probe() time, based on all the device flags and config options, it must be moved further down, just before register_netdev(), as the last config step when the config values are comitted to HW. Also, move netif_carrier_off() after register_netdev(), because it has no effect if called before. Signed-off-by: Claudiu Manoil <claudiu.manoil@freescale.com> Signed-off-by: David S.
