sfc: Add use of shared RSS contexts.
Allow PFs to allocate shared RSS contexts if we exhaust our exclusive RSS contexts. Make VFs use shared RSS contexts in all cases. Spruce up error handling so that the shadow copy of the RSS table is updated after successful update, rather than in all cases, so that we report the actual contents of the RSS table after a failure to set it, rather than what we'd like it to be. Populate context_size parameter when vacuously allocating RSS context of size 1. Signed-off-by: Shradha Shah <sshah@solarflare.com> Signed-off-by: David S. Miller <davem@davemloft.net>
