The new FW improves the packets per second rate. It required a lot of change in
the FW which implies many changes in the driver to support it. It is now also
possible for the driver to use a separate MSI-X vector for Rx and Tx - this also
add some to the complicity of this change.
All things said - after this patch, practically all performance matrixes show
improvement.
Though Vladislav Zolotarov is not signed on this patch, he did most of the job
and deserves credit for that.

The driver displays the same 0x18000000 xid for RTL_GIGA_MAC_VER_06
and RTL_GIGA_MAC_VER_05 whereas the former ought to be identified as
0x98000000.

Improve myri10ge parity error detection and recovery:
1) Don't restore PCI config space to a rebooted NIC until AFTER the
host is quiescent.
2) Let myri10ge_close() know the NIC is dead, so it won't waste time
waiting for a dead nic to respond to MXGEFW_CMD_ETHERNET_DOWN
3) When the NIC is quiet (link down, or otherwise idle link) use
a pci config space read to detect a rebooted NIC. Otherwise
we might never notice that a NIC rebooted

In general in this file, it is the status field, not the state field, that
contains values like OPEN and CLOSED. Indeed, in the first error case, it
is the field status that is initialized. I have thus assumed that all of
the error handling code should be the same, and moved it to the end of the
function to emphasize its commonality.

In all rx'd SKB cases, atalk_rcv() either eventually jumps to or falls through
to the label out:, which returns numeric 0. Numeric 0 corresponds to
NET_RX_SUCCESS, which is incorrect in failed SKB cases.
This patch makes atalk_rcv() provide the correct returns by:
o explicitly returning NET_RX_SUCCESS in the two success cases
o having the out: label return NET_RX_DROP, instead of numeric 0
o making the failed SKB labels and processing more consistent with other
_rcv() routines in the kernel, simplifying validation and removing a
backwards goto

Instead of a large (physically) linear buffer, we generate a set of
paged sk_buff, so no extra memory copy is involved. This removes
high-order allocations and saves quite a bit of memory. Phonet MTU is
65541 bytes, so the two buffers were padded to 128 kilo-bytes each.
Now, we create 17 page buffers, almost a 75% memory use reduction.

As it is, parts of the ioctl runs under the RTNL and parts of
it do not. The unlocked section is still protected by the BKL,
but there can be subtle races. For example, Eric Biederman and
Paul Moore observed that if two threads tried to create two tun
devices on the same file descriptor, then unexpected results
may occur.
As there isn't anything in the ioctl that is expected to sleep
indefinitely, we can prevent this from occurring by extending
the RTNL lock coverage.
This also allows to get rid of the BKL.
Finally, I changed tun_get_iff to take a tun device in order to
avoid calling tun_put which would dead-lock as it also tries to
take the RTNL lock.

Commit f0b3fbeae11a526c3d308b691684589ee37c359b ("FEC Buffer rework")
breaks transmission of packets where the skb data buffer is not memory
aligned according to FEC_ALIGNMENT. It incorrectly passes to
dma_sync_single() the buffer address directly from the skb, instead of
the address calculated for use (which may be the skb address or one of
the bounce buffers).
It seems there is no use converting the cpu address of the buffer to
a physical either, since dma_map_single() expects the cpu address and
will return the dma address to use in the descriptor. So remove the use
of __pa() on the buffer address as well.
This patch is against 2.6.30-rc5. This breakage is a regression over
2.6.30, which does not have this problem.
