One of the reasons for the drop of performances in the kqueue-based
poll/select is the fact that kqueue filters are called up to 3 times
per syscall and that they all spin on the NET_LOCK() for TCP/UDP
packets.
Diff below is a RFC for improving the situation.

Hi,
In filt_solisten_common() you touches `so_qlen’ only. It’s not
related to buffer and not protected by introduced `sb_mtx’ so
the solock() replacement in filt_solisten*() is wrong.
However, in filt_solisten_common() you only checks is
`so_qlen’ != 0 condition and such check could be performed
