e1000e: access multiple PHY registers on same page at the same time

2011-06-10T03:33:36+00:00

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. Signed-off-by: Bruce Allan Tested-by: Jeff Pieper Signed-off-by: Jeff Kirsher

e1000e: disable far-end loopback mode on ESB2

2011-06-10T03:31:24+00:00

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.

e1000e: implement ethtool set_phys_id

2011-04-27T09:05:53+00:00

Based on a patch from Stephen Hemminger . The new ethtool set_phys_id takes over controlling the LED for identifying boards. This fixes the lockout during that period. For this device lots of extra infrastructure can also be removed by using set_phys_id. v2: - return blink frequency for parts that do not support blink in h/w - add blink_led function pointers for devices that do support blink in h/w to cleanup the test for this functionality Signed-off-by: Bruce Allan Cc: Stephen Hemminger Tested-by: Aaron Brown Signed-off-by: Jeff Kirsher

e1000e: 82579 unaccounted missed packets

2010-09-23T03:41:20+00:00

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.

e1000e: correct MAC-PHY interconnect register offset for 82579

2010-08-03T23:40:53+00:00

The MAC-PHY interconnect register set on ICH/PCH parts is accessed through a peephole mechanism by writing an offset to a CSR register. The offset for the interconnect's half-duplex control register (which is used in a jumbo frame workaround for 82579) is incorrect.
