[PATCH] ieee82011: Added ieee80211_tx_frame to convert generic 802.11 data frames, and callbacks
tree 40adc78b623ae70d56074934ec6334eb4f0ae6a5 parent db43d847bcebaa3df6414e26d0008eb21690e8cf author James Ketrenos <jketreno@linux.intel.com> 1124445938 -0500 committer James Ketrenos <jketreno@linux.intel.com> 1127313102 -0500 Added ieee80211_tx_frame to convert generic 802.11 data frames into txbs for transmission. Added several purpose specific callbacks (handle_assoc, handle_auth, etc.) which the driver can register with for being notified on reception of variouf frame elements.
