Subject: ath9k_htc: Reduce TX queue size
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=15f6d6d52fe0d9fcf8c09788caff5d1684e5f12c;p=openwrt%2Fstaging%2Fblogic.git

ath9k_htc: Reduce TX queue size

The current max queue length of 1024 is quite large
and unnecessary. 256 suffices well enough even for high
throughput situations.
