*MAC WoW registers
back-off shift, MAC interrupt enable, magic packet enable,
pattern match enable, aifs, slot wait period, keep alive
frame failure count, beacon fail enable, beacon timeout,
keep alive timeout, auto keep alive disable,
keep alive fail disable and their corresponding
status registers. keep alive frame delay,
pattern end/byte offsets, transmit buffers for
keep alive frames and storing the user patterns
*Power Management Control registers
pme_d3cold_vaux, host_pme_enable, aux_pwr_detect,
power_state_mask, wow_pme_clear
