Make sure newer adapters are not in powerdown mode.
From Oleg Safiullin <form@pdp-11.org.ru> similiar to changes
in Linux/FreeBSD driver.

Add support for HW TCP/IP checksum offload for adapters that support it.

Has been in snaps for weeks too with noone complaining so far.

Correct the WOL magic value and rename NFE_WOL_MAGIC to NFE_WOL_ENABLE.

WOL magic value from Peer Chen@NVIDIA via FreeBSD.

- remove ETHER_MAX_LEN_JUMBO and ETHERMTU_JUMBO.
- use if_hardmtu for MTU ioctl handlers.

increase the Tx ring count from 64 to 256.

Use %b in error flag printfs to describe meaning of error bits.

re-enable interrupt mitigation and mask out NFE_IRQ_TIMER that was causing
interrupts flood.

unlikely that we will see mbuf chains with 62 fragments anytime soon

- remove mbuf linearization code. it is broken in this context and it is very
unlikely that we will see mbuf chains with 62 fragments anytime soon
(anyway, it would not crash, it would just freeze TX).
- fix max scatter value so we don't end up filling the ring with one mbuf
chain.

- stop enabling/disabling interrupts in nfe_intr().

initial jumbo frames support (disabled for now).
#define'ing NFE_NO_JUMBO can save a few hundred KB of wired memory.

- call nfe_ifmedia_upd() early in nfe_init() to reset the PHY.
- set RX buffer size register properly

force a wakeup of the MAC in nfe_init().
this makes my MCP51 board working.

committed over a nfe.

reorganize descriptors flags declarations; it was very confusing.
no binary change.

- start MII timer in nfe_init() and move timer initialization in nfe_attach()
- set RX filter before enabling RX in nfe_init()
- call mii_down() in nfe_stop()

Initial bits for an nvidia nforce Ethernet driver.
bus_dma usage modelled after ral. Does not yet see rx interrupts
when testing with ck804.

Nvidia won't give out documentation for this, various "free" operating
systems include a closed source driver, and the Linux people who reverse
engineered it to create a specification won't give it out.
