Use the netdevice transmit lock via netif_tx_lock rather than putting
lock in device specific code and using lockless transmit. The code is
cleaner using netif_tx_lock, and the performance is same.

Since a transmit can take several control blocks, the old code waited
until the last control block was marked as done. This code processes
the return values incrementally. This makes slots in the tx ring available
and less chance of getting stuck.

Several minor issues exist in the low-level device handling code of
e1000. The NVM and EEPROM writing/reading code was updated which fixes
unneeded delays, adds proper eeprom aqcuiring steps and handle shadow
ram and flash access. Minor cosmetic adjustments to the polarity code
adding symbols. PHY reset code mistakenly distinguished between MAC
types instead of PHY types, and was fixes.

We were plagued by our interrupt handler posting a watchdog event which
could occur when our adapter was going down in case a late packet arrived
just before e1000_down() finished. This caused the watchdog timer to start
after the NIC was down and keep rescheduling it every N seconds. Once
the driver unloaded it would panic.

Unify our shutdown/suspend/resume code and make it similar to e1000:
e1000_shutdown now calls suspend which does the exact same thing on
shutdown except saving PCI config state on suspend. WoL setup code
is now also more simple and works even when CONFIG_PM is not set, which
was previously broken.

The purpose of this patch is to split off the case when a device does
not reply on the lower level (which is reported by HC hardware), and
a case when the device accepted the request, but does not reply at
upper level. This redefinition allows to diagnose issues easier,
without asking the user if the -110 happened "immediately".
The usbmon splits such cases already thanks to its timestamp, but
it's not always available.
I adjusted all drivers which I found affected (by searching for "urb").
Out of tree drivers may suffer a little bit, but I do not expect much
breakage. At worst they may print a few messages.

Add modalias attribute support for the almost forgotten now EISA bus and
(at least some) EISA-aware modules.
The modalias entry looks like (for an 3c509 NIC):
eisa:sTCM5093
and the in-module alias like:
eisa:sTCM5093*
The patch moves struct eisa_device_id declaration from include/linux/eisa.h
to include/linux/mod_devicetable.h (so that the former now #includes the
latter), adds proper MODULE_DEVICE_TABLE(eisa, ...) statements for all
drivers with EISA IDs I found (some drivers already have that DEVICE_TABLE
declared), and adds recognision of __mod_eisa_device_table to
scripts/mod/file2alias.c so that proper modules.alias will be generated.
There's no support for /lib/modules/$kver/modules.eisamap, as it's not used
by any existing tools, and because with in-kernel modalias mechanism those
maps are obsolete anyway.
The rationale for this patch is:
a) to make EISA bus to act as other busses with modalias
support, to unify driver loading
b) to foget about EISA finally - with this patch, kernel
(who still supports EISA) will be the only one who knows
how to choose the necessary drivers for this bus ;)

The following patches reduce the size of the VFS inode structure by 28 bytes
on a UP x86. (It would be more on an x86_64 system). This is a 10% reduction
in the inode size on a UP kernel that is configured in a production mode
(i.e., with no spinlock or other debugging functions enabled; if you want to
save memory taken up by in-core inodes, the first thing you should do is
disable the debugging options; they are responsible for a huge amount of bloat
in the VFS inode structure).
This patch:
The filesystem or device-specific pointer in the inode is inside a union,
which is pretty pointless given that all 30+ users of this field have been
using the void pointer. Get rid of the union and rename it to i_private, with
a comment to explain who is allowed to use the void pointer. This is just a
cleanup, but it allows us to reuse the union 'u' for something something where
the union will actually be used.

Add logic to check ARP request / reply packets used for ARP
monitor link integrity checking.
The current method simply examines the slave device to see if it
has sent and received traffic; this can be fooled by extraneous traffic.
For example, if multiple hosts running bonding are behind a common
switch, the probe traffic from the multiple instances of bonding will
update the tx/rx times on each other's slave devices.
