Re: [PATCH 1/2] mac80211: Save sk_pacing_shift to ieee80211_hw

[Wen Gong <wgong@codeaurora.org>]

Thanks,
I will add description of tx_sk_pacing_shift as below and sent next 
patch.
*
* @tx_sk_pacing_shift: The TCP stack allow more than a single ms of data
*     to be queued in the stack. The value is a bit-shift of 1 second, 
e.g. 8
*     is ~4ms of queued data. It only affects local TCP sockets.
