Fix a problem with Tulip 21142 HP branded PCI cards (PN#: B5509-66001),
which feature a NatSemi DP83840A PHY.
Without that patch, it is impossible to properly initialize the card's PHY,
and it's thus impossible to monitor/configure it.

The patch below moves the init_block out of the private struct and
only allocates init block with pci_alloc_consistent.
This has two effects:
1. Performance increase for non cache coherent machines, because the
CPU only data in the private struct are now cached
2. locks are working now for platforms, which need to have locks
in cached memory

Function `phy_mii_ioctl' returns physical device's information based on
user requests. When requested to return the basic mode control register
information (BMCR), the original implementation only returns the physical
device's duplex information and forgets to return speed information, which
should not be because BMCR register is used to hold both duplex and speed
information.
The patch checks the BMCR value against speed-related flags and fills the
return structure's speed field accordingly.

Use the round_jiffies() function in e1000.
These timers all were of the "about once a second" or "about once every X
seconds" variety and several showed up in the "what wakes the cpu up" profiles
that the tickless patches provide. Some timers are highly dynamic based on
network load; but even on low activity systems they still show up so the
rounding is done only in cases of low activity, allowing higher frequency
timers in the high activity case.
The various hardware watchdogs are an obvious case; they run every 2 seconds
but aren't otherwise specific of exactly when they need to run.

Current tc35815 driver is very obsolete and less maintained for a long
time. Replace it with a new driver based on one from CELF patch
archive.
Major advantages of CELF version (version 1.23, for kernel 2.6.10) are:
* Independent of JMR3927.
(Actually independent of MIPS, but AFAIK the chip is used only on
MIPS platforms)
* TX4938 support.
* 64-bit proof.
* Asynchronous and on-demand auto negotiation.
* High performance on non-coherent architecture.
* ethtool support.
* Many bugfixes and cleanups.
And improvoments since version 1.23 are:
* TX4939 support.
* NETPOLL support.
* NAPI support. (disabled by default)
* Reduce memcpy on receiving.
* PM support.
* Many cleanups and bugfixes.

Just found a hole in my last patch. It was reported to me that shortly after we
integrated this patch. The report was of an oops that took place inside of
netif_rx when using the sis900 driver. Looking at my origional patch I noted
that there was a spot between the new skb_alloc and the refill_rx_ring label
where skb got reassigned to the pointer currently held in the rx_ring for the
purposes of receiveing the frame. The result of this is however that the buffer
that gets passed to netif_rx (if it is called), then gets placed right back into
the rx_ring. So if you receive frames fast enough the skb being processed by
the network stack can get corrupted. The reporter is testing out the fix I've
written for this below (I'm not near my hardware at the moment to test myself),
but I wanted to post it for review ASAP. I'll post test results when I hear
them, but I think this is a pretty straightforward fix. It just uses a separate
pointer to do the rx operation, so that we don't improperly reassign the pointer
that we use to refill the rx ring.

The subsystem rwsem is not used by the driver core at all, so the use of

Fixed tun/tap driver's handling of hw addresses. The hw address is stored
in both the net_device.dev_addr and tun.dev_addr fields. These fields were
not kept synchronized, and in fact weren't even initialized to the same
value. Now during both init and when performing SIOCSIFHWADDR on the tun
device these values are both updated. However, if SIOCSIFHWADDR is
performed on the net device directly (for instance, setting the hw address
using ifconfig), the tun device does not get updated. Perhaps the
tun.dev_addr field should be removed completely at some point, as it is
redundant and net_device.dev_addr can be used anywhere it is used.
