Alexander Duyck 0cce119aa9 igb: cleanup flow control configuration to make requested/current more clear
This patch cleans up the flow control configuration for igb to make it a
bit more readable in regards to what the requested and current modes are.
This should help with the maintainability of the current igb driver in
regards to flow control.

Alexander Duyck 28fc06f58b igb: move all multicast addresses into multicast table array
This patch moves all of the multicast addresses out of the free Receive
address registers and instead programs them all into the multicast table
array.  As a result the multicast filtering may not be as precise, but it
also greatly reduces the overhead for multicast addresses.

Alexander Duyck 009bc06e53 igb: add completion timeout workaround for 82575/82576
The 82575 and 82576 hardware can both experience data corruption issues if
a pci-e completion arrives after the timeout value.  In order to avoid this
we need to increase the timeout value while pci-e master is disabled.

Alexander Duyck dcc3ae9a52 igb: remove media type fiber as it is misleading
The current igb driver only supports copper and serdes.  The fiber media
type is a holdover from earlier NICs as the current nics supported by igb
all use serdes when communicating over a fiber connection.  As a result we
can remove media type fiber without losing any functionality.

Alexander Duyck 85e8d004ec igb: transition driver to only using advanced descriptors
Currently the driver uses advanced descriptors for its main functionality,
but then uses legacy when testing.  This patch changes this so that
advanced descriptors are used throughout and all mentions of legacy
descriptors are removed.

Auke Kok 9d5c824399 igb: PCI-Express 82575 Gigabit Ethernet driver
We are pleased to announce a new Gigabit Ethernet product and its
driver to the linux community. This product is the Intel(R) 82575
Gigabit Ethernet adapter family. Physical adapters will be available
to the public soon. These adapters come in 2- and 4-port versions
(copper PHY) currently. Other variants will be available later.

The 82575 chipset supports significantly different features that
warrant a new driver. The descriptor format is (just like the
ixgbe driver) different. The device can use multiple MSI-X vectors
and multiple queues for both send and receive. This allows us to
optimize some of the driver code specifically as well compared to
the e1000-supported devices.

This version of the igb driver no lnger uses fake netdevices and
incorporates napi_struct members for each ring to do the multi-
queue polling. multi-queue is enabled by default and the driver
supports NAPI mode only.

All the namespace collisions should be gone in this version too. The
register macro's have been condensed to improve readability.
