wil6210: support 8KB RX buffers
The 11ad spec requires 11ad devices to be able to receive 8KB
packets over the air. Currently this is only possible by
loading the driver with mtu_max=7912 but this also forces
a smaller block ACK window size which reduces performance
for stations which transmit normal sized packets (<2KB).
Fix this problem as follows:
1. Add a module parameter rx_large_buf that when set,
will allocate 8KB RX buffers regardless of mtu_max
setting.
2. When receiving block ACK request agree to any window
size not above our maximum, regardless of the mtu_max setting.
This means if the other side transmits small packets (2KB)
it can still set up block ACK with a large window size,
and get better performance.
