[PATCH] RPC: add generic interface for adjusting the congestion window
A new interface that allows transports to adjust their congestion window
using the Van Jacobson implementation in xprt.c is provided.
Test-plan:
Use WAN simulation to cause sporadic bursty packet loss. Look for
significant regression in performance or client stability.
