wil6210: Add support for setting RBUFCAP configuration
RBUFCAP support added in FW.
The RBUFCAP feature is amendment to the block ack mechanism to
prevent overloading of the recipient’s memory space, which may
happen in case the link speed is higher than STA’s capability
to process or consume incoming data.
The block ack policy (ba_policy) is now controlled by FW so driver
should ignore this field.
Add new debugfs "rbufcap" to configure RBUFCAP.
