[PATCH] RPC: separate xprt_timer implementations
Allow transports to hook the retransmit timer interrupt. Some transports
calculate their congestion window here so that a retransmit timeout has
immediate effect on the congestion window.
Test-plan:
Use WAN simulation to cause sporadic bursty packet loss. Look for significant
regression in performance or client stability.
