ipcpd-eth: Tune raw sockets and retry queries
Add IPCP_ETH_SNDBUF/RCVBUF cmake build options so deployments can size
the AF_PACKET socket buffers without patching code. Drop the
O_NONBLOCK fcntl on the raw socket in favour of per-recvfrom
MSG_DONTWAIT so race-loser reader threads exit with EAGAIN without
spamming the log.
Track frame send failures and the SO_SNDBUF size in the eth/summary
RIB; log a one-shot warning when the kernel reports AF_PACKET drops.
Retry name queries up to NAME_QUERY_RETRIES times within
NAME_QUERY_TIMEO; a single lost ARP-style mgmt frame no longer fails
the query. Bump IRMd QUERY_TIMEOUT from 200 ms to 2200 ms so the IRMd
budget exceeds the new shim retry window.
