This patch adds the following log messages to help debugging
failure cases:
1) log FW version number: this is useful when driver initialization
fails and the FW version number cannot be queried via ethtool
2) per function resource limits for BEx chips: these values are
currently being printed only for Skyhawk and Lancer
3) PCI BAR mapping failure
4) function_mode/caps queried from FW: this helps catch any FW bugs
that could advertise wrong capabilities to the driver

This patch adds support for slave_changelink to the bonding and uses it
to give the ability to change the queue_id of the enslaved devices via
netlink. It sets slave_maxtype and uses bond_changelink as a prototype for
bond_slave_changelink.
Example/test command after the iproute2 patch:
 ip link set eth0 type bond_slave queue_id 10

When Broadcom tags are enabled, e.g: when interfaced to an Ethernet
switch, make sure that we tell the RXCHK engine that it should be
expecting a 4-bytes Broadcom tag after the Ethernet MAC Source Address.

Use netdev_uses_dsa() to check for that condition since that will tell
us if a switch is attached to our network interface.

This patch:
 - Clarifies the specific requirements of devices returning
   CHECKSUM_UNNECESSARY (comments in skbuff.h).
 - Adds csum_level field to skbuff. This is used to express how
   many checksums are covered by CHECKSUM_UNNECESSARY (stores n - 1).
   This replaces the overloading of skb->encapsulation, that field is
   is now only used to indicate inner headers are valid.
 - Change __skb_checksum_validate_needed to "consume" each checksum
   as indicated by csum_level as layers of the the packet are parsed.
 - Remove skb_pop_rcv_encapsulation, no longer needed in the new
   csum_level model.

	i)  Fast mode (takes about 690 ms)
	ii) Medium mode (takes about 2930 ms)
	iii) Slow mode (takes about 7500 ms)

To run POST, firmware file with name "83xx_post_fw.bin" should be present under
/lib/firmware directory. load_fw_file module parameter is used to specify
POST operation and its speed mode.
load_fw_file = 2 : Fast mode
load_fw_file = 3 : Medium mode
