Andrew Gallatin 9ba117960e Fix a memory leak when ip_output_send() returns EAGAIN due to send tag issues ... When ip_output_send() returns EAGAIN due to issues with send tags (route change, lagg failover, etc), it must free the mbuf. This is because ip_output_send() was written as a wrapper/replacement for a direct call to if_output(), and the contract with if_output() has historically been that it owns the mbufs once called. When ip_output_send() failed to free mbufs, it violated this assumption and lead to leaked mbufs. This was noticed when using NIC TLS in combination with hardware rate-limited connections. When seeing lots of NIC output drops triggered ratelimit send tag changes, we noticed we were leaking ktls_sessions, send tags and mbufs. This was due ip_output_send() leaking mbufs which held references to ktls_sessions, which in turn held references to send tags. Many thanks to jbh, rrs, hselasky and markj for their help in debugging this.
