Subject: rt2x00: only set TXDONE_FALLBACK in rt2800pci if the frame was retried
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=ecb7cab59a2b8c0ec1aab6ac903def1d5a81d32b;p=linux-beck.git

rt2x00: only set TXDONE_FALLBACK in rt2800pci if the frame was retried

TXDONE_FALLBACK expresses that fallback rates were used for retries. Hence,
it only makes sense to set the flag if retries > 0.
