iw: Allow configuring empty legacy and ht ratesets.

From: Ben Greear <[email protected]>

This allows one to configure exactly one rate for drivers such as ath10k that will only allow a single rate to be configured.

Hello,

But iw already support setting single rate with ath10k. This is example from ath10k commit log:

Example:
iw wlanX set bitrates legacy-5 ht-mcs-5 vht-mcs-5 2:9 will setup VHT, nss=2, mcs=9

iw wlanX set bitrates legacy-5 18 ht-mcs-5 vht-mcs-5 will setup legacy, 18Mbps

iw wlanX set bitrates legacy-5 ht-mcs-5 3 vht-mcs-5 will setup HT, nss=1, mcs=3

iw wlanX set bitrate legacy-5 ht-mcs-5 vht-mcs-5 1:0-9 will setup nss=1

iw wlanX set bitrate legacy-5 ht-mcs-5 vht-mcs-5 1:0-9 2:0-9 will setup nss=2

Ahh, I see. I was confused about what syntax to use for 'iw', must have typo'd something early on and then though the limitation was in the parser.

Thanks,
Ben
