Move the code into PHY oriented functions, and for that a new structure
is defines for each PHY which contain PHY properties and its own
functions. This also enables to encapsulate all PHY specific operations
into the PHY functions. During initialization, the PHYs will be probed
by the "bnx2x_phy_probe" function to detect which PHYs exist on-board,
and configure them accordingly. Note that the ext_phy_reset
implementation was incorporated in the ext_phy_init since it is actually
part of the PHY initialization procedure.

This patch enables TCP checksum offload support for IPv6 on ibmveth.

improvement when an MTU of 64000 was used.
This featured is enabled by default, as is the case for IPv4 checksum
offload. When checksum offload is enabled the driver will negotiate
IPv4 and IPv6 offload with the firmware separately and enable what
is available. As long as either IPv4 or IPv6 offload is supported
and enabled the device will report that checksum offload is enabled.
The device stats, available through ethtool, will display which
checksum offload features are supported/enabled by firmware.
Performance testing against a stock kernel shows no regression for IPv4
or IPv6 in terms of throughput or processor utilization with checksum
disabled or enabled.

All skbs given to network stack had their ip_summed set to

The reason is driver sets skb->ip_summed on the original skb before the
copy eventually done by copybreak. The fresh skb gets the ip_summed =
CHECKSUM_NONE value, forcing network stack to recompute checksum, and
preventing my GRO patch to work.
Fix is to make the ip_summed setting after skb copy.

ipv6: add special mode accept_ra=2 to accept RA while configured as router
The current IPv6 behavior is to not accept router advertisements while
forwarding, i.e. configured as router.
This does make sense, a router is typically not supposed to be auto
configured. However there are exceptions and we should allow the
current behavior to be overwritten.
Therefore this patch enables the user to overrule the "if forwarding
enabled then don't listen to RAs" rule by setting accept_ra to the
special value of 2.
An alternative would be to ignore the forwarding switch alltogether
and solely accept RAs based on the value of accept_ra. However, I

strange unwanted behavior therefore we it seems wise to only do so

bnx2x: Change BCM848xx configuration according to IEEE
Change BCM848xx behavior to fit IEEE such that setting 10Mb/100Mb will
use force speed, and setting 1Gb/10Gb will use auto-negotiation with the
specific speed advertised

bnx2x: Fix potential link issue In BCM8727 based boards
In BCM8727 based boards, setting default 10G link speed after link was
set to 1G may lead to link down issue. The problem was setting the right
value, but to the wrong registers

Hypervisor allows, two VM's interfaces to have same mac address.
These VM's interfaces get differentiate with Vlan tag.
This patch add support to learn and configure mac+vlan filter on device.

Device eswitch need to configure with VM's mac address.
Hypervisor doesn't provide any utility/callbacks to get VM's mac address.
Unicast mac address filter improves performance and also provide
packet loopback capability i.e communication between VM.
Above features is by default off, can be turned on with module parameter
'mac_learn'.

net: add a comment on netdev->last_rx
As some driver authors seem to reintroduce dev->last_rx use,
add a comment to strongly discourage this.
Since commit 6cf3f41e6c0 (bonding, net: Move last_rx update into bonding
recv logic), network drivers dont need to update last_rx themselves,
unless they use this field to implement a timeout.
Not updating last_rx helps not dirtying a cache line, improving
performance in SMP.
