kern_sig.c: ANSIfy and remove archaic register keyword Sponsored by: The FreeBSD Foundation MFC r318389 (by emaste): Remove register keyword from sys/ and ANSIfy prototypes A long long time ago the register keyword told the compiler to store the corresponding variable in a CPU register, but it is not relevant for any compiler used in the FreeBSD world today. ANSIfy related prototypes while here. Reviewed by: cem, jhb Sponsored by: The FreeBSD Foundation Differential Revision: https://reviews.freebsd.org/D10193

Add support for the TP-Link TG-3468 v2. This is an RTL8168 chip, which we already support so all we have to do is add the vendor ID. PR: 212876 Submitted by: Tobias Kortkamp

sys/dev: minor spelling fixes.

Most affect comments, very few have user-visible effects.

sys/dev: use our nitems() macro when it is avaliable through param.h.

before their initial configuration is done, it turns out that r281337 has the inverse effect on some older chips. Moreover, as with newer chips before, two chips seemingly identical according to their MAC revisions may behave differently in this regard, with most working but a few not, making changes extremely hard to test. Closer inspection of the corresponding Linux code suggests that RX and TX should only be enabled after their initial configuration with RTL8168G and later chips, i. e. RTL8106E{,US}, RTL8107E, as well as RTL8168{EP,G,GU,H}, so limit the new code path to these. [1] - Distinguish between RTL8168H and RTL8107E, with the latter being the 10/100-Mbit/s-only variant of the former. - For MAC variants that can only do Fast Ethernet at a maximum, ensure that we don't advertise Gigabit Ethernet speed. - In re_stop(), do the inverse of re_init_locked() and enable RXDV gate on RTL8168G and later chips again, matching what Linux does.
