This commit introduces additional platform-dependent checking when the kernel returns an error. Previously, the session is terminated when PingFrame sends a discovery packet larger than the limit. With this commit, the error is checked, and if it is "datagram too large", the error is ignored. Additionally, 1. This commit re-enables MTU discovery on Windows unless it is disabled explicitly by user (Undo #3276), 2. Set IP_DONTFRAGMENT and IPV6_DONTFRAG with error checking on Windows, and 3. Set IP_MTU_DISCOVERY to PMTUDISC_DO for both IPv4 and IPv6 on Linux so that the kernel will return "message too long". Fixes #3273 #3327
