Fix and update battery status bits according to linux driver

MFC r234617:

Do not announce IPv6 TSO support yet. The in-tree driver does not seem
to fully handle this yet.

MFC 229613:
Update recently added drivers to use the if_*addr_r*lock() wrapper
functions instead of using the IF_ADDR_LOCK directly. The wrapper
functions are the supported interface for device drivers.

MFC r229423:

In sys/dev/qlxgb/qla_misc.c, fix a copy/paste issue. Clang complained
the variable 'val' was uninitialized when used. Instead, 'sig' should
have been printed.

The maximum TSO frame size should be:
maximum IP datagram size (65535 bytes) +
Ethernet header size (14 bytes) +
2 * VLAN tag size (4 bytes) [1].

[1] We need to multiply by 2 to account for the double VLAN tag
provision added in IEEE 802.1ad.
