Subject: ath9k: Setup short preamble properly in rate registration
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=f46730d13f23b4578dca1c0f7663ea3093ff4f0e;p=linux-beck.git

ath9k: Setup short preamble properly in rate registration

This patch fixes an issue where hw_value_short was not being filled
with the proper ratecode during rate registration, but was being used
in the RX path for decoding the packet rate.
