ftp(1) from vendor/tnftp always tried the following for
every TCP connection:
1. Get the current buffer length of SO_SNDBUF and SO_RCVBUF
by getsockopt(2).
2. Invoke setsockopt(2) to set them to the same values
after checking if they are in a range between 8 KiB to 8 MiB.
This behavior broke dynamic buffer sizing enabled by
default (net.inet.tcp.{recv,send}buf_auto sysctls) and
led to a very poor transfer rate. The fetch(1) utility
does not have this problem.
This change prevents SO_SNDBUF and SO_RCVBUF from configuring
when the buffer auto-sizing is enabled unless the buffer sizes are
explicitly specified.
