Subject: ath9k: fix too early enabling of rx during ath_startrecv()
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=952949738aba19f84dae9def18e0baa58f0ce0b8;p=openwrt%2Fstaging%2Fblogic.git

ath9k: fix too early enabling of rx during ath_startrecv()

rx should only be enabled after enough rx buffers have been given to the
hardware, however ath_rx_buf_link was calling ath9k_hw_rxena after every
single added buffer.
Fix this by calling ath9k_hw_rxena directly from the rx tasklet after
completion instead.
