ixgbe: implement DCB ops dcb_ieee_del()

2011-06-25T07:15:58+00:00

ixgbe: remove unused fcoe.tc field and fcoe_setapp()

2011-06-25T07:15:42+00:00

The fcoe.tc field is no longer used so remove it. After the field is removed there is no need to keep fcoe_setapp() around so remove it as well. And finally we can get rid of some DCB #ifdef's in the fcoe code. Signed-off-by: John Fastabend Tested-by: Ross Brattain Signed-off-by: Jeff Kirsher

ixgbe: complete FCoE initialization from setapp() routine

2011-06-25T07:15:24+00:00

Commit, commit c8ca76ebc6e50752c5311b92bb9aef7edb324577 Author: John Fastabend Date: Sat Mar 12 03:50:53 2011 +0000 ixgbe: DCB, further cleanups to app configuration Removed the getapp() routines from ixgbe because they are no longer needed. It also allowed the set hardware routines to use both IEEE 802.1Qaz app types and CEE app types. This added code to do bit shifting in the IEEE case. This patch reverts the checks and handles the IEEE case from the setapp entry point. I prefer this because it keeps the two paths from having to be aware of the DCB mode. This resolves a bug where I missed setting the selector bit in the IEEE spec value and left it in the CEE value. Now that they are separate routines these types of errors should not occur.

ixgbe: fix flags relating to perfect filters to support coexistence

2011-06-24T05:43:53+00:00

I am removing the requirement that Ntuple filters have the same number of queues and requirements as ATR. As a result this change will make it so that all the Ntuple flag does is disable ATR for now. This change fixes an issue in which we were incorrectly re-enabling ATR when we exited perfect filter mode. This was due to the fact that the logic assumed RSS and DCB were mutually exclusive which is no longer the case. To correct this we just need to add a check to guarantee DCB is disabled before re-enabling ATR. Signed-off-by: Alexander Duyck Tested-by: Ross Brattain Signed-off-by: Jeff Kirsher

ixgbe: configure minimal packet buffers to support TC

2011-06-21T08:19:54+00:00

ixgbe devices support different numbers of packet buffers either 8 or 4. Here we only allocate the minimal number of packet buffers required to implement the net_devices number of traffic classes. Fewer traffic classes allows for larger packet buffers in hardware. Also more Tx/Rx queues can be given to each traffic class. This patch is mostly about propagating the number of traffic classes through the init path. Specifically this adds the 4TC cases to the MRQC and MTQC setup routines. Also ixgbe_setup_tc() was sanitized to handle other traffic class value. Finally changing the number of packet buffers in the hardware requires the device to reinit. So this moves the reinit work from DCB into the main ixgbe_setup_tc() routine to consolidate the reset code. Now dcbnl_xxx ops call ixgbe_setup_tc() to configure packet buffers if needed.

ixgbe: DCB, further cleanups to app configuration

2011-04-14T02:19:47+00:00

With the app data on the kernel dcb_app list we no longer need to specifically handle them in ixgbe for the CEE case. So now we can remove app handling logic and check when the hw is configured if the app data matches the hardware configuration in set_hw_all(). If it does not match then we can reconfigure.
