Under heavy load, the EOTID termination FLOWC request fails to get enqueued to the end of the Tx ring due to lack of credits. This results in EOTID leak. When disabling TC-MQPRIO offload, the link is already brought down to cleanup EOTIDs. So, flush any pending enqueued skbs that can't be sent outside the wire, to make room for FLOWC request.

2020-04-01cxgb4: fix MPS index overwrite when setting MAC addressHerat Ramani1-1/+0
cxgb4_update_mac_filt() earlier requests firmware to add a new MAC address into MPS TCAM. The MPS TCAM index returned by firmware is stored in pi->xact_addr_filt. However, the saved MPS TCAM index gets overwritten again with the return value of cxgb4_update_mac_filt(), which is wrong. When trying to update to another MAC address later, the wrong MPS TCAM index is sent to firmware, which causes firmware to return error, because it's not the same MPS TCAM index that firmware had sent earlier to driver. So, fix by removing the wrong overwrite being done after call to cxgb4_update_mac_filt().

2020-03-20cxgb4: fix Txq restart check during backpressureRahul Lakkireddy1-2/+8
Driver reclaims descriptors in much smaller batches, even if hardware indicates more to reclaim, during backpressure. So, fix the check to restart the Txq during backpressure, by looking at how many descriptors hardware had indicated to reclaim, and not on how many descriptors that driver had actually reclaimed. Once the Txq is restarted, driver will reclaim even more descriptors when Tx path is entered again.
