The 82599 EEPROM supports alternative prefix for World Wide Node Name
(WWNN) and World Wide Port Name (WWPN). The prefixes can be used together
with the SAN MAC address to form the WWNN and WWPN, which can be used by
upper layer drivers such as Fiber Channel over Ethernet (FCoE).

In mii monitor mode, bond_check_dev_link() calls the the ioctl
handler of slave devices. It stores the ndo_do_ioctl function
pointer to a static (!) ioctl variable and later uses it to call the
handler with the IOCTL macro.
If another thread executes bond_check_dev_link() at the same time
(even with a different bond, which none of the locks prevent), a
race condition occurs. If the two racing slaves have different
drivers, this may result in one driver's ioctl handler being
called with a pointer to a net_device controlled with a different
driver, resulting in unpredictable breakage.
Unless I am overlooking something, the "static" must be a
copy'n'paste error (?).

Devices with loadable firmware must have their firmware reloaded
after the system resumes from sleep, but the request_firmare()
API is not available at this point in the resume flow because
tasks are not yet running, and the system will hang if it is
called. Work around this issue by only calling request_firmware()
for a device's first firmware load, and cache a copy of the pointer
to the firmware blob for that device, so that we may reload firmware
images even during resume.
