In MMIO dumps of ndiswrapper there are following PHY ops:
phy_read(0x0118) -> 0x013d
phy_read(0x01ed) -> 0x993d
phy_read(0x0119) -> 0x012f
phy_read(0x01ee) -> 0x992f
phy_read(0x011a) -> 0x0139
phy_read(0x0969) -> 0x9939
It matches the code of wlc_phy_txpower_est_power_nphy (from brcm80211),
so we know the registers meaning.

After b43_phy_ht_tx_power_ctl_setup there are some extra radio ops:
 radio_read(0x08bf) -> 0x0001
radio_write(0x08bf) <- 0x0001
radio_write(0x0159) <- 0x0011
On N-PHY we write 0x11 to TSSI regs, so it's probably sth similar.

After comparing writes to registers at 0x000, 0x400 and 0x800 it seems
there are many very similar writes. So 0x000 offset is not for accessing
something totally different, but probably just the first out of three
cores.

beacon_ie buffer is allocated in mwifiex_fill_new_bss_desc()

beacon_ie is freed before the function returns. However,

Fix it by freeing beacon_ie (bss_desc->beacon_buf) in
