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.

IPv4 would work with this driver only with static arp table entries,
the patch reverts a padto introduced in
commit 26a17b7bbb
sc92031: start transmit return value bugfix
The padto does not work because the driver code evaluates `len' later on and
there are cases where skb->len is not updated accordingly.
This was observed with ARP frames (skb->len = 42 bytes, !skb_cloned(),
skb_tailroom = 84 bytes). Then in skb_pad(), the first condition is true, where
skb->len is not updated. As a consequence, the driver uses 42 bytes instead of
the 60 bytes, and the ARP frame never makes it onto the wire.

Use netdev_alloc_skb since it handles any NUMA node memory localtion issues
and sets skb->dev. Since device driver was not setting skb->dev, I bet
filter rules based on device would not work.

Any negative return value from start_xmit is interpreted as NETDEV_TX_LOCK
which is not what this driver wants. It should return 0 (NETDEV_TX_OK)
when it consumes a packet.
Also, use skb_padto() as the generic way to pad small frames.

For the operations
get-tx-csum
get-sg
get-tso
get-ufo
the default ethtool_op_xxx behavior is fine for all drivers, so we
permit op==NULL to imply the default behavior.
This provides a more uniform behavior across all drivers, eliminating
ethtool(8) "ioctl not supported" errors on older drivers that had
not been updated for the latest sub-ioctls.
The ethtool_op_xxx() functions are left exported, in case anyone
wishes to call them directly from a driver-private implementation --
a not-uncommon case. Should an ethtool_op_xxx() helper remain unused
for a while, except by net/core/ethtool.c, we can un-export it at a
later date.

All drivers implement ethtool get_perm_addr the same way -- by calling
the generic function. So we can inline the generic function into the
caller and avoid going through the drivers.

This is a driver for the Silan SC92031/Rsltek 8139D NIC chip.
This chip is found on at least one counterfeit Encore ENL832-TX-RENT NIC
[1], which came with a mini-CD with the 2.4 driver. A slightly older
version of the driver was found at [2]. The main difference between them
is that the newer one has a small bugfix in the RX path, a lot of
gratuitous renaming of functions, all the printable strings changed to show
as a "Rsltek 8139D" [sic], and a PCI ID of 8139 instead of 2031. The
driver on this patch is a rewrite of the vendor drivers (based mostly on
the older one).
Changes from the previous patch sent to netdev:
- Use MMIO instead of PIO
- Changed TX bounce buffers allocation
- Use skb_copy_and_csum_dev
- Several small bug fixes
- Tested for more than just a few minutes each time
[1] See http://www.encore-usa.com/faq.php under ENL832-TX-RENT for more
information
[2] Look for SL_LINUX.ZIP (which is really a .tar.gz) at
http://broadbandforum.in/dataone_Intex_LAN_cardlinux-t4207-s15.html
[3] To compile on 2.6.17, simply add back the last argument to the
interrupt handler in two places, and copy the boolean declarations
from 2.6.19
