Subject: Only increment xretries statistic for unicast frames
X-Git-Url: https://jxself.org/git/?a=commitdiff_plain;ds=sidebyside;h=97217c1250772c3c6dbba8b00bab70df6dbd22da;hp=97217c1250772c3c6dbba8b00bab70df6dbd22da;p=open-ath9k-htc-firmware.git

Only increment xretries statistic for unicast frames

It looks like the ar5416 only has the AR_ExcessiveRetries flag
to let the outside know it didn't receive an ACK.

So in case of broadcast/multicast it gets set even though it's
not "excessive retry" per se. These frames just don't
acknowledge/retry in a 802.11 transmission.

This patch makes sure broadcast/multicast transmissions won't
increment the xretries statistic.
