The first wrb seen by tx compl processing does not have a dma handle in it.
Currently, pci_unmap_single() is attempted on this wrb and pci_unmap_page() on the
rest. So, pci_unmap_page() gets incorrectly called on the dma hdl of skb->data (that
was mapped using map_single()). This patch fixes this issue.

This change removes the extra configuration we were doing on the mdicnfg
register which should be set by EEPROM and which we should not need to
write again afterwards.  This code was a holdover from some earlier

and is no longer needed now that the production EEPROMs are in place.

There is no point to align or pad mibs to cache lines, they are per cpu
allocated with a 8 bytes alignment anyway.
This wastes space for no gain. This patch removes __SNMP_MIB_ALIGN__

Since SNMP mibs contain "unsigned long" fields only, we can relax the
allocation alignment from "unsigned long long" to "unsigned long"

Its currently hard to diagnose when ACK frames are dropped because an
application set TCP_DEFER_ACCEPT on its listening socket.

See http://bugzilla.kernel.org/show_bug.cgi?id=15507

This patch adds a SNMP value, named TCPDeferAcceptDrop

netstat -s | grep TCPDeferAcceptDrop
    TCPDeferAcceptDrop: 0

This counter is incremented every time we drop a pure ACK frame received
by a socket in SYN_RECV state because its SYNACK retrans count is lower
than defer_accept value.

This patch reduces timer events while keeping accuracy by rounding
our timer and/or batching several address validations in addrconf_verify().

addrconf_verify() is called at earliest timeout among interface addresses'
timeouts, but at maximum ADDR_CHECK_FREQUENCY (120 secs).

In most cases, all of timeouts of interface addresses are long enough
(e.g. several hours or days vs 2 minutes), this timer is usually called
every ADDR_CHECK_FREQUENCY, and it is okay to be lazy.
(Note this timer could be eliminated if all code paths which modifies
variables related to timeouts call us manually, but it is another story.)

However, in other least but important cases, we try keeping accuracy.

When the real interface address timeout is coming, and the timeout
is just before the rounded timeout, we accept some error.

When a timeout has been reached, we also try batching other several
events in very near future.
