ed848e3a02 Only Tx checksum offloading is supported now. Remove experimental
code sneaked in r199611.

9955274c64 Add IPv4/TCP/UDP Tx checksum offloading support. It seems the
controller also has support for IP/TCP checksum offloading for Rx
path. But I failed to find to way to enable Rx MAC to compute the
checksum of received frames.

abd12fc6d6 Because we know received bytes including CRC there is no reason to
call m_adj(9). The controller also seems to have a capability to
strip CRC bytes but I failed to activate this feature except for
loopback traffic.

26e07b50c6 Add initial endianness support. It seems the controller supports
both big-endian and little-endian format in descriptors for Rx path
but I couldn't find equivalent feature in Tx path. So just stick to
little-endian for now.

8b3c64969b Use capability pointer to access PCIe registers rather than
directly access them at fixed address. Frequently the register
offset could be changed if additional PCI capabilities are added to
controller.
One odd thing is ET_PCIR_L0S_L1_LATENCY register. I think it's PCIe
link capabilities register but the location of the register does
not match with PCIe capability pointer + offset. I'm not sure it's
shadow register of PCIe link capabilities register.

23263665d5 Remove complex macros that were used to compute bits values.
Although these macros may have its own strength, its complex
definition make hard to read the code.

eb956cd041 Use if_maddr_rlock()/if_maddr_runlock() rather than IF_ADDR_LOCK()/
IF_ADDR_UNLOCK() across network device drivers when accessing the
per-interface multicast address list, if_multiaddrs.  This will
allow us to change the locking strategy without affecting our driver
programming interface or binary interface.

For two wireless drivers, remove unnecessary locking, since they
don't actually access the multicast address list.
