The above mentioned patch alone. because removing disable_11b_rates() from p2p_init
might affect firmware based drivers like ath9k_htc. So for the drivers that have
rate control in the firmware, we can disable 11b rates at init. Somwhow we need
to expose the driver capabilities to wpa_s to identify this. For other drivers
11b rates can be disabled on iface change. Is that fine?
