Guo-Fu Tseng ce7d70af2c jme: Tuning rxsum function
1. Use more efficient way to determine flag status.
2. Hardware dose not mark fragment bit against IPv6 packets,
   print TCP/UDP checksum warning message for IPv4 packets
   only.

Guo-Fu Tseng d1dfa1d1de jme: Remove shadow register support
The hardware failed to update the shadow register in several cases.
It's known to be failed at 64bit box with more than 4G RAM.
In order to make the device working stable, give up using the shadow
register feature.

Eric Dumazet cdd0db058d net: dont update dev->trans_start
Second round of drivers for Gb cards (and NIU one I forgot in the 10GB round)

Now that core network takes care of trans_start updates, dont do it
in drivers themselves, if possible. Drivers can avoid one cache miss
(on dev->trans_start) in their start_xmit() handler.

Exceptions are NETIF_F_LLTX drivers

Yang Hongyang e930438c42 Replace all DMA_nBIT_MASK macro with DMA_BIT_MASK(n)
This is the second go through of the old DMA_nBIT_MASK macro,and there're not
so many of them left,so I put them into one patch.I hope this is the last round.
After this the definition of the old DMA_nBIT_MASK macro could be removed.

When the napi api was changed to separate its 1:1 binding to the net_device
struct, the netif_rx_[prep|schedule|complete] api failed to remove the now
vestigual net_device structure parameter.  This patch cleans up that api by
properly removing it..

akeemting 4f40bf4689 jme: GHC register control fix for new hardware
Due to the hardware design, except the first chip on the market,
other chips needs to setup the clock source for MAC processor
implicitly through Global Host Control Register(GHC).
(Strange design huh?)

10/100M uses the PCI-E as clock source, and 1G uses GPHY.

And I reordered the code a little, to make it easier to read.

Harvey Harrison 31c221c49f net: jme.c rxdesc.flags is __le16, other missing endian swaps
This is the minimal patch to fix endian mismatches.  These are
probably bugs on big-endian arches, noops on little endian.

jme_rxsum_ok could be improved to directly take a __le16 and
change all of the masks/sets to be in little-endian, but
has not been done here to keep the patch small.

David S. Miller babcda74e9 drivers/net: Kill now superfluous ->last_rx stores.
The generic packet receive code takes care of setting
netdev->last_rx when necessary, for the sake of the
bonding ARP monitor.

Drivers need not do it any more.

Some cases had to be skipped over because the drivers
were making use of the ->last_rx value themselves.
