v2:
patch2: store the cb_priv of representor to the flow_block_cb->indr.cb_priv
in the driver. And make the correct check with the statments
this->indr.cb_priv == cb_priv
patch4: del the driver list only in the indriect cleanup callbacks
v3:
add the cover letter and changlogs.
v4:
collapsed 1/4, 2/4, 4/4 in v3 to one fix
Add the prepare patch 1 and 2
This series fixes commit 1fac52da5942 ("net: flow_offload: consolidate
indirect flow_block infrastructure") that revists the flow_block
infrastructure.
patch #1 #2???prepare for fix patch #3
add and use flow_indr_block_cb_alloc/remove function
patch #3: fix flow_indr_dev_unregister path
If the representor is removed, then identify the indirect flow_blocks
that need to be removed by the release callback and the port representor
structure. To identify the port representor structure, a new
indr.cb_priv field needs to be introduced. The flow_block also needs to
be removed from the driver list from the cleanup path
patch#4 fix block->nooffloaddevcnt warning dmesg log.
When a indr device add in offload success. The block->nooffloaddevcnt
should be 0. After the representor go away. When the dir device go away
the flow_block UNBIND operation with -EOPNOTSUPP which lead the warning
demesg log.
The block->nooffloaddevcnt should always count for indr block.
even the indr block offload successful. The representor maybe
gone away and the ingress qdisc can work in software mode.
