sys/dev/pci : if_iwx.c if_iwxreg.h
Log message:
Let iwx(4) firmware decide which Tx rate to use.
The firmware will notify the driver when it decides to change Tx rate.
Based on those notifications the driver updates the value displayed by
ifconfig. This is similar to how bwfm(4) and urtwn(4) handle this.
Offloading Tx rate selection should allow us to eventually delete AMRR/MiRA
support code from iwx(4). That code is disabled for now, not yet deleted.
For now, the driver restricts firmware Tx rate selection to 11n/20MHz mode
because that's what net80211 can support.
