The HTT RX ring is replenished with a maximum of 16 buffers,
but this might be insufficient when RX traffic is high.
Not having enough RX buffers throttles the FW, resulting
in low throughput.
This patch adds a module parameter to adjust the fill size
based on the platform/usage.
I don't think this should be adjustable.
Default value of 16 causes rx ring corruption within 1 hour of stress
testing. Increasing this limit to 1000 solves the issue, not sure what
max value in > 16 and <= 1000 works. This lower value obviously has issues
on some platforms.
