From d38b13aa7884021ddb06fb6f248da265b8a6fbee Mon Sep 17 00:00:00 2001 From: Malcolm Priestley Date: Wed, 25 Jun 2014 21:14:23 +0100 Subject: staging: vt6656: mac80211 conversion: Create tx functions Create vnt_fill_txkey as mac80211 replacement for s_vFillTxKey. Create vnt_tx_packet which a merger of s_bPacketToWirelessUsb, nsDMA_tx_packet and csMgmt_xmit using mac80211 signalling. Create vnt_beacon_xmit as mac80211 replacement for csBeacon_xmit. Changing header in vnt_beacon_buffer to struct ieee80211_mgmt deleting some of old code. vnt_beacon_make is needed to make beacon for vnt_beacon_xmit. Create vnt_beacon_enable as mac80211 call to enable beacon. vnt_fill_ieee80211_rts is modified to use struct ieee80211_hdr instead of struct ethhdr and access to tx_context.
