Commit Message

Hariprasad Kelam Feb. 10, 2023, 11:10 a.m. UTC
From: Subbaraya Sundeep <sbhatta@marvell.com>

Current implementation is such that the number of Send queues (SQs)
are decided on the device probe which is equal to the number of online
cpus. These SQs are allocated and deallocated in interface open and c
lose calls respectively.

This patch defines new APIs for initializing and deinitializing Send
queues dynamically and allocates more number of transmit queues for
QOS feature.
