2011-06-30enic: Add support to configure hardware interrupt coalesce timers in a platform independent wayVasanthy Kolluri11-26/+122
enic driver and the underlying hardware use different units for representing the interrupt coalesce timer. Driver converts the interrupt coalesce timer in usec to hardware cycles while setting the relevant hardware registers. The conversion factor can be different for each of the adapter hardware types. So it is dynamically learnt from the adapter firmware using the devcmd CMD_INTR_COAL_CONVERT. This allows the driver to configure the hardware interrupt coalesce timers in a platform independent way.

2011-06-09enic: Pass 802.1p bits for packets tagged with vlan zeroVasanthy Kolluri1-2/+1
enic driver currently passes 802.1p bits to the upper layers for packets tagged with non-zero vlan ids only. This patch extends such behaviour to zero vlan tagged packets also. The patch is dependant on the following kernel patches: 1) vlan_dev: VLAN 0 should be treated as "no vlan tag" (802.1p packet) - net-next-2.6 git commit: ad1afb00393915a51c21b1ae8704562bf036855f - Available 2.6.36 and later 2) vlan: Centralize handling of hardware acceleration. - net-next-2.6 git commit: 3701e51382a026cba10c60b03efabe534fba4ca4 - Available 2.6.37 and later Signed-off-by: Christian Benvenuti <benve@cisco.com> Signed-off-by: Danny Guo <dannguo@cisco.com> Signed-off-by: Vasanthy Kolluri <vkolluri@cisco.com> Signed-off-by: Roopa Prabhu <roprabhu@cisco.com> Signed-off-by: David Wang <dwang2@cisco.com> Signed-off-by: David S.

2011-04-29ethtool: cosmetic: Use ethtool ethtool_cmd_speed APIDavid Decotigny1-2/+2
This updates the network drivers so that they don't access the ethtool_cmd::speed field directly, but use ethtool_cmd_speed() instead. For most of the drivers, these changes are purely cosmetic and don't fix any problem, such as for those 1GbE/10GbE drivers that indirectly call their own ethtool get_settings()/mii_ethtool_gset(). The changes are meant to enforce code consistency and provide robustness with future larger throughputs, at the expense of a few CPU cycles for each ethtool operation.

2011-03-30enic: Add support for PORT_REQUEST_PREASSOCIATE_RRRoopa Prabhu5-149/+344
Current enic code only supports ASSOCIATE and DISASSOCIATE port profile operations. This patch adds enic support for port profile PORT_REQUEST_PREASSOCIATE_RR operation. The VIC adapter (8021qbh) is capable of handling port profile requests done in two steps namely PREASSOCIATE_RR and ASSOCIATE today. The motivation to support PREASSOCIATE_RR comes mainly from its use as an optimization during VM migration ie, to do resource reservation on destination host before resources on source host are released. PREASSOCIATE_RR is a VDP operation and according to the latest at IEEE, 8021qbh will also need to support VDP commands. In addition to handling the new PORT_REQUEST_PREASSOCIATE_RR operation this patch also does the below: - Introduces handlers for PORT_REQUEST operations - Moves most of the port profile handling code to new files enic_pp.[ch] - Uses new fw devcmds for port profile operations Signed-off-by: Roopa Prabhu <roprabhu@cisco.com> Signed-off-by: David Wang <dwang2@cisco.com> Signed-off-by: Christian Benvenuti <benve@cisco.com> Signed-off-by: David S.

2011-02-17enic: Always use single transmit and single receive hardware queues per deviceVasanthy Kolluri2-4/+4
We believe that our earlier patch for supporting multiple hardware receive queues per enic device requires more internal testing. At this point, we think that it's best to disable the use of multiple receive queues. The current patch provides an effective means for the same. Also, we continue to disallow multiple hardware transmit queues per device. But change the way we enforce this in order to maintain consistency with the way receive queues are handled.

As a result of which a client calling enic_get_vf_port to get the status of port profile disassociate will always get a return value of ENODATA. This patch renames ENIC_SET_APPLIED to more appropriate ENIC_PORT_REQUEST_APPLIED and reverts back the recent change so that the flag is set both at associate and disassociate of a port profile.

flush_scheduled_work() is on its way out. This patch contains simple conversions to replace flush_scheduled_work() usage with direct cancels and flushes. Directly cancel the used works on driver detach and flush them in other cases. The conversions are mostly straight forward and the only dangers are, * Forgetting to cancel/flush one or more used works. * Cancelling when a work should be flushed (ie. the work must be executed once scheduled whether the driver is detaching or not). I've gone over the changes multiple times but it would be much appreciated if you can review with the above points in mind. Signed-off-by: Tejun Heo <tj@kernel.org> Cc: "David S.
