Bert Kenward 46d054f8f5 sfc: clear napi_hash state when copying channels ... efx_copy_channel() doesn't correctly clear the napi_hash related state. This means that when napi_hash_add is called for that channel nothing is done, and we are left with a copy of the napi_hash_node from the old channel. When we later call napi_hash_del() on this channel we have a stale napi_hash_node. Corruption is only seen when there are multiple entries in one of the napi_hash lists. This is made more likely by having a very large number of channels. Testing was carried out with 512 channels - 32 channels on each of 16 ports. This failure typically appears as protection faults within napi_by_id() or napi_hash_add(). efx_copy_channel() is only used when tx or rx ring sizes are changed (ethtool -G).
