Avoid undefined behavior when reset the chip. found by kUBSan.

 Add missing ifioctl_common() for SIOCSIFFLAGS to make if_flags controllable.

Make et(4) work:
- Enabling TX/RX in et_init() will always fail when cable is not plugged in,
  if this happens, we delay TX/RX enablement until link is up. From FreeBSD.
- Modify flow control stuff a little (from FrerBSD). It still doesn't work.
- KNF. Part of OpenBSD 1.12.
