2013-09-23bnx2x: 57840 non-external loopback test fail on 1GYaniv Rosner
when 1G-optic module was plugged in, internal loopback test failed because the driver used to check the optic module (with no need), and for 1G optic module, the link speed was forced down to 1G, while the XMAC (10G MAC) was enabled. This patch avoid accessing optic module in case internal loopback was selected, and update the link speed in case 1G optic module was detected during init stage.

2013-09-23bnx2x: KR2 disablement fixYaniv Rosner
Relocate bnx2x_disable_kr2 function, and use it to disable KR2 in case it is not configured in order to clear it's configuration, otherwise the link may come up at 20G instead of the requested 10G-KR. In addition, restart AN after disabling KR2 as part of the KR2 work-around.

2013-09-23bnx2x: Generalize KR work-aroundYaniv Rosner
Previously, in case of KR link down, the driver would reset the PHY and restart auto negotiation only when old Warpcore microcode was used (below D108). This patch comes to generalize this by keep trying to restart KR link, regardless of Warpcore microcode, since it was found that it solves another link issue which source is a link-partner. As part of this change, the signal detect is no longer a condition to apply the work-around to cover this new case. Like before, as long as the link is down, AN will be restarted every 2 seconds.

2013-09-06bnx2x: Restore a call to config_initEilon Greenstein
Commit c0a77ec74f295013d7ba3204dd3ed25fccf83cb4 'bnx2x: Add missing braces in bnx2x:bnx2x_link_initialize' identified indentation problem, but resolved it by adding braces instead of fixing the indentation. The braces now prevents a config_init call in some cases, though it should be called regardless of that condition. This patch removes the braces and fix the confusing indentation that caused this mess.

2013-03-08bnx2x: Fix intermittent long KR2 link up timeYaniv Rosner
When a KR2 device is connected to a KR link-partner, sometimes it requires disabling KR2 for the link to come up. To get a KR2 link up later, in case no base pages are seen, the KR2 is restored. The problem was that some link partners cleared their advertised BP/NP after around two seconds, causing the driver to disable/enable KR2 link all the time. The fix was to wait at least 5 seconds before checking KR2 recovery. Signed-off-by: Yaniv Rosner <yanivr@broadcom.com> Signed-off-by: Eilon Greenstein <eilong@broadcom.com> Signed-off-by: David S.

2012-12-07bnx2x: Prevent link flaps when booting from SAN.Barak Witkowski
It is possible that the driver is configured to operate with a certain link configuration which differs from the link's configuration during boot from SAN - this would cause the driver to flap the link. Said flap may be missed by specific switches, causing dcbx convergence to be too long and boot sequence to fail. Convergence is longer because switch ignores new dcbx packets due to counters mismatch, as only host side reset the counters due to the link flap. This patch causes the driver to ignore user's initial configuration during boot from SAN, and continues with the existing link configuration.

Taking PHY lock is not required on some older designs, but we are removing this complication and always taking it since it is always required on newer designs and does not worth the code complication on the older boards. Taking PHY lock was initially required only on specific boards which had their MDC/MDIO bus crossed, but since this lock is now always required, for example, when NCSI is present, the PHY lock will always be taken.

Per measurements, the SFP+ suffered from small current leakage in two cases: - When no module was plugged and TX laser was disabled. The fix was to enable it, and when module is plugged in, check if it needs to be disabled. - When over-current event occurs due to invalid SFP+ module, the HW basically shuts down the current for this module, but the SW needs to complete this by issuing a power down via a GPIO.

2012-11-28bnx2x: Change MDIO clock settingsYaniv Rosner
When drivers works on top of an old bootcode, it is theoretically subjected to MDC/MDIO failures since the MDIO clock is set in the beginning of each sequence, rather than per CL45 command. On rare cases an old bootcodes may change that in the middle, so to address that, the MDIO clock is set for each CL45 access. In addition, setting the MDIO clock is now done per EMAC base, and not per port number, since a specific port can potentially use both EMACs for different PHY accesses.

This patch moves the bnx2x and cnic drivers into using FW 7.8.2 which was recently submitted into the linux-firmware tree. A short summary of minor bugs fixed by this FW: 1. In switch dependent mode, fix several issues regarding inner vlan vs. DCB priorities. 2. iSCSI - not all packets were completed on a forward channel. 3. DCB - fixed for 4-port devices. 4. Fixed false parity reported in CAM memories when operating near -5% on the 1.0V core supply. 5. ETS default settings are set to fairness between traffic classes (rather than strict priority), and uses the same chip receive buffer configuration for both PFC and pause.

2012-09-13bnx2x: Link Flap AvoidanceYaniv Rosner
Various flows in the bnx2x driver cause a link-flap - if the link is up, it would be toggled down (after a mac/phy reset) and then taken back up. In many of these cases, there is no need to do cause such a flap, as the associated flows should not actually affect the link. This patch adds the 'Link Flap Avoidance' mechanism, which allows the driver to better determine if a given flow requires a link change, and thus minimize the number of link flaps caused by the driver.
