2014-09-05cnic : Cleanup CONFIG_IPV6 & VLAN checkAnish Bhatt2-3/+3
The cnic module needs to ensure that if ipv6 support is compiled as a module, then the cnic module cannot be compiled as built-in as it depends on ipv6.

2014-09-02bnx2x: Configure device endianity on driver load and reset endianity on removal.Manish Chopra1-18/+39
Some hosts can be both little and big endian. In certain scenarios a big endian kernel can kexec a little endian kernel. This patch fixes this case from both ends: 1) Return endianity to original values on shutdown (in case little endian kernel boots after we shutdown). 2) Do not rely on HW reset values when loading driver in little endian kernel but configure them explicitly (in case previous kernel was big endian and did not reset the HW).

2014-09-02tg3: prevent ifup/ifdown during PCI error recoveryIvan Vecera2-0/+17
The patch fixes race conditions between PCI error recovery callbacks and potential ifup/ifdown. First, if ifup (tg3_open) is called between tg3_io_error_detected() and tg3_io_resume() then tp->timer is armed twice before expiry. Once during tg3_open() and again during tg3_io_resume(). This results in BUG at kernel/time/timer.c:945. Second, if ifdown (tg3_close) is called between tg3_io_error_detected() and tg3_io_resume() then tg3_napi_disable() is called twice without a tg3_napi_enable between. Once during tg3_io_error_detected() and again during tg3_close(). The tg3_io_resume() then hangs on rtnl_lock(). v2: Added logging messages per Prashant's request Cc: Prashant Sreedharan <[email protected]> Cc: Michael Chan <[email protected]> Signed-off-by: Ivan Vecera <[email protected]> Acked-by: Prashant Sreedharan <[email protected]> Signed-off-by: David S.

2014-08-21bnx2x: Revert UNDI flushing mechanismYuval Mintz1-75/+17
Commit 91ebb929b6f8 ("bnx2x: Add support for Multi-Function UNDI") [which was later supposedly fixed by de682941eef3 ("bnx2x: Fix UNDI driver unload")] introduced a bug in which in some [yet-to-be-determined] scenarios the alternative flushing mechanism which was to guarantee the Rx buffers are empty before resetting them during device probe will fail. If this happens, when device will be loaded once more a fatal attention will occur; Since this most likely happens in boot from SAN scenarios, the machine will fail to load. Notice this may occur not only in the 'Multi-Function' scenario but in the regular scenario as well, i.e., this introduced a regression in the driver's ability to perform boot from SAN. The patch reverts the mechanism and applies the old scheme to multi-function devices as well as to single-function devices.

2014-08-11net: bcmgenet: correctly resume adapter from Wake-on-LANFlorian Fainelli1-4/+6
In case we configured the adapter to be a wake up source from Wake-on-LAN, but we never actually woke up using Wake-on-LAN, we will leave the adapter in MagicPacket matching mode, which prevents any other type of packets from reaching the RX engine. Fix this by calling bcmgenet_power_up() with GENET_POWER_WOL_MAGIC to restore the adapter configuration in bcmgenet_resume(). The second problem we had was an imbalanced clock disabling in bcmgenet_wol_resume(), the Wake-on-LAN slow clock is only enabled in bcmgenet_suspend() if we configured Wake-on-LAN, yet we unconditionally disabled the clock in bcmgenet_wol_resume().

2014-08-11net: bcmgenet: update UMAC_CMD only when link is detectedFlorian Fainelli1-2/+6
When we bring the interface down, phy_stop() will schedule the PHY state machine to call our link adjustment callback. By the time we do so, we may have clock gated off the GENET hardware block, and this will cause bus errors to happen in bcmgenet_mii_setup(): Make sure that we only touch the UMAC_CMD register when there is an actual link. This is safe to do for two reasons: - updating the Ethernet MAC registers only make sense when a physical link is present - the PHY library state machine first set phydev->link = 0 before invoking phydev->adjust_link in the PHY_HALTED case Fixes: 240524089d7a ("net: bcmgenet: only update UMAC_CMD if something changed") Signed-off-by: Florian Fainelli <[email protected]> Signed-off-by: David S.

Make sure that we properly suspend and resume the PHY device when we enter low power modes. We had two calls to bcmgenet_mii_reset() which will issue a software-reset to the PHY without using the PHY library, get rid of them since they are completely bogus and mess up with the PHY library state. Make sure that we reset the PHY library cached values (link, pause and duplex) to allow the link adjustment callback to be invoked when needed.

2014-08-11net: bcmgenet: request and enable main clock earlierFlorian Fainelli1-7/+7
bcmgenet_set_hw_params() will read the hardware version and compare it with the one we are getting from Device Tree. Due to the clock being enabled too late, bcmgenet_set_hw_params() will cause bus errors since the GENET hardware block is still gated off by the time bcmgenet_set_hw_params() is called, this will also make us fail the version check since we will read the value 0 from the hardware.
