net/bnxt: fix double free in port start failure

During port start when bnxt_start_nic() fails, it tries to free
"intr_handle->intr_vec" but the variable is not set to NULL after that.
If port start fails, driver invokes bnxt_dev_stop() which will lead
to a double free of "intr_handle->intr_vec".

Fix it by removing the call to free "intr_handle->intr_vec" in the

3 years agonet/mlx5: fix drop action for Direct Rules/Verbs
Viacheslav Ovsiienko [Mon, 5 Apr 2021 09:59:01 +0000 (09:59 +0000)]
net/mlx5: fix drop action for Direct Rules/Verbs

There are multiple branches in rdma-core library backing
the rte flows:
  - Verbs
  - Direct Verbs (DV)
  - Direct Rules (DR)

The Verbs API always requires the specifying the queue even
if there is the drop action in the flow, though the kernel
optimizes out the actual queue usage for the flows containing
the drop action. The PMD handles the dedicated Rx queue to
provide Verbs API compatibility.

The DV/DR API does not require explicit specifying the queue
at the flow creation, but PMD still specified the dedicated
drop queue as action. It performed the packet forwarding to
the dummy queue (that was not polled at all) causing the
steering pipeline resources usage and degrading the overall
packet processing rate. For example, with inserted flow to
drop all the ingress packets the statistics reported only
15Mpps of 64B packets were received over 100Gbps line.

Since the Direct Rule API for E-Switch was introduced the
rdma-core supports the dedicated drop action, that is recognized
both for DV and DR and can be used for the entire device in
unified fashion, regardless of steering domain. The similar drop
action was introduced for E-Switch, the usage of this one can be
extended for other steering domains, not for E-Switch's one only.

This patch:
  - renames esw_drop_action to dr_drop_action to emphasize
    the global nature of the variable (not only E-Switch domain)
  - specifies this global drop action instead of dedicated
    drop queue for the DR/DV flows
