From: Ajit Khaparde Date: Wed, 2 Oct 2019 23:25:46 +0000 (-0700) Subject: net/bnxt: support RSS action X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=adc0f81c6552d18be4d0ebc964c38bfe5fc26b2a;p=dpdk.git net/bnxt: support RSS action Add support for RSS action during flow creation. group id should not be 0 when RSS action is specified. Driver will return an error for such a flow. If a group id is used to create a filter with “n” RSS queues, it cannot be used to create a filter with a different number of RSS queues till all the flows using that combination are deleted. While creating a flow if a group id groups a certain Rx queue ids for RSS, the same group id shall not create a flow with a different group of Rx queue ids till all the flows belonging to the group ids are deleted. While creating a flow if a group id groups a certain Rx queue ids for RSS, the same queue ids shall not be used with a different group id till all flows created with that group id are deleted.
