Subject: minstrel_ht: enable frame aggregation for fixed rate
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=2a9e6c58871df77b69afffad250062853570ee23;p=linux-beck.git

minstrel_ht: enable frame aggregation for fixed rate

When sample_idx is set to a value other than -1 it activates
the IEEE80211_TX_CTL_RATE_CTRL_PROBE flag which disables
frame aggregation. To allow frame aggregation during fixed
rate it is necessary to set max_tp_rate, max_tp_rate2 and
max_prob_rate instead of sample_idx.
