RPS currently depends on SMP and SYSFS

Adding a CONFIG_RPS makes sense in case this requirement changes in the
future. This patch saves about 1500 bytes of kernel text in case SMP is
on but SYSFS is off.

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.

Nowadays, most distributions enable netconsole by default,

The igb driver was incorrectly attempting to write to registers that do not
exist on 82580 hardware.  This wasn't causing any issues that I can tell,
but it is not recommended behavior either so I have changed this so we are
determining which registers to write to based on mac type.

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
development work that was being done on a board with an incomplete EEPROM
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.

After the type change, addresses in unicast and multicast lists wouldn't make
