2018-10-02cxgb4: Use proper enum in cxgb4_dcb_handle_fw_updateNathan Chancellor1-2/+2
Clang warns when one enumerated type is implicitly converted to another. drivers/net/ethernet/chelsio/cxgb4/cxgb4_dcb.c:303:7: warning: implicit conversion from enumeration type 'enum cxgb4_dcb_state' to different enumeration type 'enum cxgb4_dcb_state_input' [-Wenum-conversion] ?

- In CXGB4_DCB_STATE_FW_INCOMPLETE state check if the dcb version is changed and update the dcb supported version. - Also, fill the priority code point value for priority based flow control. Signed-off-by: Ganesh Goudar <ganeshgr@chelsio.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2015-07-21cxgb4 : Allow firmware DCB info to be queried in host stateAnish Bhatt1-11/+21
Since finally DCB traffic management is still handled by firmware, allow firmware to be fully programmed and queried even in host managed state for the cases where this was previously rejected. Signed-off-by: Anish Bhatt <anish@chelsio.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2014-11-21cxgb4 : Fix DCB priority groups being returned in wrong orderAnish Bhatt1-1/+1
Peer priority groups were being reversed, but this was missed in the previous fix sent out for this issue. v2 : Previous patch was doing extra unnecessary work, result is the same. Please ignore previous patch Fixes : ee7bc3cdc270 ('cxgb4 : dcb open-lldp interop fixes') Signed-off-by: Anish Bhatt <anish@chelsio.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2014-11-12cxgb4 : dcb open-lldp interop fixesAnish Bhatt1-9/+19
* In LLD_MANAGED mode, traffic classes were being returned in reverse order to lldp agent. * Priotype of strict is no longer the default returned. * Change behaviour of getdcbx() based on discussions on lldp-devel These were missed as there was no working fetch interface for open-lldp when running in LLD_MANAGED mode till now.

2014-11-10cxgb4 : Fix bug in DCB app deletionAnish Bhatt1-1/+2
Unlike CEE, IEEE has a bespoke app delete call and does not rely on priority for app deletion Fixes : 2376c879b80c ('cxgb4 : Improve handling of DCB negotiation or loss thereof') Signed-off-by: Anish Bhatt <anish@chelsio.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2014-10-27cxgb4 : Handle dcb enable correctlyAnish Bhatt1-1/+6
Disabling DCBx in firmware automatically enables DCBx for control via host lldp agents. Wait for an explicit setstate call from an lldp agents to enable DCBx instead.

2014-10-27cxgb4 : Improve handling of DCB negotiation or loss thereofAnish Bhatt1-3/+45
Clear out any DCB apps we might have added to kernel table when we lose DCB sync (or IEEE equivalent event). These were previously left behind and not cleaned up correctly. IEEE allows individual components to work independently, so improve check for IEEE completion by specifying individual components.

2014-08-07cxgb4: IEEE fixes for DCBx state machineAnish Bhatt1-70/+190
* Changes required due to 16eecd9be4b05 ("dcbnl : Fix misleading dcb_app->priority explanation") * Driver was previously not aware of what DCBx version was negotiated by firmware, this could lead to DCB app table in kernel or in firmware being populated wrong since IEEE/CEE used different formats made clear by above mentioned commit * Driver was missing a couple of state transitions that could be caused by other drivers that use chelsio hardware, resulting in incorrect behaviour (the change that addresses this also flips the state machine to switch on state instead of transition, hope this is okay in current window) * Prio queue info & tsa is no longer thrown away v2: Print DCBx state transition messages only when debug is enabled Signed-off-by: Anish Bhatt <anish@chelsio.com> Signed-off-by: David S.
