Doing a PHY page select can take a long time, relatively speaking. This can cause a significant delay when updating a number of PHY registers on the same page by unnecessarily setting the page for each PHY access. For example when going to Sx, all the PHY wakeup registers (WUC, RAR[], MTA[], SHRAR[], IP4AT[], IP6AT[], etc.) on 82577/8/9 need to be updated which takes a long time which can cause issues when suspending. This patch introduces new PHY ops function pointers to allow callers to set the page directly and do any number of PHY accesses on that page. This feature is currently only implemented for 82577, 82578 and 82579 PHYs for both the normally addressed registers as well as the special- case addressing of the PHY wakeup registers on page 800. For the latter registers, the existing function for accessing the wakeup registers has been divided up into three- 1) enable access to the wakeup register page, 2) perform the register access and 3) disable access to the wakeup register page. The two functions that enable/disable access to the wakeup register page are necessarily available to the caller so that the caller can restore the value of the Port Control (a.k.a. Wakeup Enable) register after the wakeup register accesses are done. All instances of writing to multiple PHY registers on the same page are updated to use this new method and to acquire any PHY locking mechanism before setting the page and performing the register accesses, and release the locking mechanism afterward. Some affiliated magic number cleanup is done as well.

The ESB2 LAN includes a debug feature that enables far-end loopback (FELB) of the SerDes/Kumeran interface. This feature is activated when receiving a sequence of symbols that includes a reserved codeword. On a perfect link, FELB would never be activated. In the presence of bit errors, there is a very small, but non-zero, probability of FELB being activated. If the FELB is activated, the SerDes link becomes non-functional and must be reset. It could also corrupt the switching tables in the switch since the ESB2 is transmitting packets with a different source MAC address. This patch disables the FELB feature.

On 82579, there is a hardware bug that can cause received packets to not get transferred from the PHY to the MAC due to K1 (a power saving feature of the PHY-MAC interconnect similar to ASPM L1). Since the MAC controls the accounting of missed packets, these will go unnoticed. Workaround the issue by setting the K1 beacon duration according to the link speed.

The MAC-PHY interconnect on 82577/82578 uses a power management feature (called K1) which must be disabled when in 1Gbps due to a hardware issue on these parts. The #define bit setting used to enable/disable K1 is incorrect and can cause PHY register accesses to stop working altogether until the next device reset. This patch sets the register correctly. This issue is present in kernels since 2.6.32.

The mac->arc_subsystem was being incorrectly used to flag whether or not manageability was enabled when it should only be used to state whether the ARC (Host interface) subsystem is available on a particular MAC _and_ only valid when any manageability is enabled. The ARC subsystem is currently only available on 80003es2lan and 82573 parts supported by the driver. A new flag, has_fwsm, is introduced to be used when checking if manageability is enabled but only on parts that acutally have an FWSM register. While the above parts have an FWSM register, there are other parts that have FWSM but do not have support for the ARC subsystem, namely 82571/2 and ICHx/PCH. And then there are parts that have manageability, but do not have either FWSM register or support for the ARC subsystem - these are 82574 and 82583. For 80003es2lan, 82571/2/3 and ICH/PCH parts, this patch makes no functional changes, it only corrects the usage of the manageability flags. For 82574 and 82583, it fixes the incorrect accesses of the non-existent FWSM register and ARC subsystem as well as corrects the check for management pass-through.

This patch rewrites the PHY power up/down code to fit with the family- specific style used in the driver. All pre-existing calls to power up or down the PHY remain untouched.

PCH-based parts (82577/82578) and some ICH8-based parts (82566) need to hold the swflag (sw/fw/hw hardware semaphore) over consecutive PHY accesses in order to perform sw-driven PHY configuration during initialization to workaround known hardware issues (see follow-on patch). This patch provides new PHY read/write functions (and function pointers) that will allow accessing the PHY registers assuming the swflag has already been acquired. The actual PHY register access code has moved into helper functions that are called with a flag indicating whether or not the swflag has already been acquired and acquires/releases it if not. The functions called from within the updated PHY access functions had to be updated to assume the swflag was already acquired, and other functions that called those functions were also updated to acquire/release the swflag.

Phy corruption has been observed on 2-port 82571 adapters, and is root-caused to lack of synchronization between the 2 driver instances, which conflict when attempting to access the phy via the single MDIC register. A semaphore exists for this purpose, and is now used on these designs. Because PXE &/or EFI boot code (which we cannot expect to be built with this fix) may leave the inter-instance semaphore in an invalid initial state when the driver first loads, this fix also includes a one-time (per driver load) fix-up of the semaphore initial state.
