I experience similar problem. After boot msk0 status is active, but I'm
not able to send anything:
% ping 172.21.21.21
PING 172.21.21.21 (172.21.21.21): 56 data bytes
ping: sendto: No buffer space available
ping: sendto: No buffer space available

After unplugging cable and putting it back everything works as
expected:
% ping 172.21.21.21
PING 172.21.21.21 (172.21.21.21): 56 data bytes
64 bytes from 172.21.21.21: icmp_seq=0 ttl=64 time=0.904 ms

It is 100% reproducible, running recent current.

Thanks.
