netinet/in.h: add INADDR_DUMMY from linux v5.13

2022-03-08T22:21:26+00:00

see

  linux commit 321827477360934dc040e9d3c626bf1de6c3ab3c
  icmp: don't send out ICMP messages with a source address of 0.0.0.0

"RFC7600 reserves a dummy address to be used as a source for ICMP
messages (192.0.0.8/32), so let's teach the kernel to substitute that
address as a last resort if the regular source address selection procedure
fails."
