Several small fixes around negative test case of the insertion of a
IXGBE_ERR_NOT_SUPPORTED module.
- mdio45_probe call was always failing due to mdio.prtad not being
set. The function set to mdio.mdio_read was still working as we just
happen to always be at prtad == 0. This will allow us to set the phy_id
and phy.type correctly now.
- There was timing issue with i2c calls when initiated from a tasklet.
A small delay was added to allow the electrical oscillation to calm down.
- Logic change in ixgbe_sfp_task that allows NOT_SUPPORTED condition
to be recognized.

We need to set/clear the mac address register when the link goes up/down
respectively. Without this both ports of a 2-port device can end up
with the same mac address in a bonding scenario.
The new ql_link_on() and ql_link_off() will also be used in handling
certain firmware events.

This addes functionality to set/clear the MAC address in the hardware
when the link goes up/down.
The MAC address register is persistent across function resets. In
bonding the same address can bounce from one port to the other. This
can cause packets to be delivered to the wrong port.
This patch clears the MAC address in the hardware when the link is down
and sets it when the link comes up.
It was found that pulling/pushing the cable from one port to another
causes the same MAC address to be in both ports.
The next patch in this series will use this functionality as well.

The hardware semaphore covers the configuration register as well as the
ICB registers. The ICB high and low regs contain the address of the
initialization control block and the config register is used to signal
the hardware that a block is ready to be downloaded. Currently we were
only protecting the ICB regs. This changes expands to cover the config
register as well.

There's a bug in addrconf_prefix_rcv() where it won't update the
preferred lifetime of an IPv6 address if the current valid lifetime
of the address is less than 2 hours (the minimum value in the RA).
For example, If I send a router advertisement with a prefix that
has valid lifetime = preferred lifetime = 2 hours we'll build
this address:
3: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qlen 1000
inet6 2001:1890:1109:a20:217:8ff:fe7d:4718/64 scope global dynamic
valid_lft 7175sec preferred_lft 7175sec
If I then send the same prefix with valid lifetime = preferred
lifetime = 0 it will be ignored since the minimum valid lifetime
is 2 hours:
3: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qlen 1000
inet6 2001:1890:1109:a20:217:8ff:fe7d:4718/64 scope global dynamic
valid_lft 7161sec preferred_lft 7161sec
But according to RFC 4862 we should always reset the preferred lifetime
even if the valid lifetime is invalid, which would cause the address
to immediately get deprecated. So with this patch we'd see this:
5: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qlen 1000
inet6 2001:1890:1109:a20:21f:29ff:fe5a:ef04/64 scope global deprecated dynamic
valid_lft 7163sec preferred_lft 0sec
The comment winds-up being 5x the size of the code to fix the problem.
Update the preferred lifetime of IPv6 addresses derived from a prefix
info option in a router advertisement even if the valid lifetime in
the option is invalid, as specified in RFC 4862 Section 5.5.3e. Fixes
an issue where an address will not immediately become deprecated.
