Subject: [dpdk-dev] [PATCH v2 6/8] common/cnxk: set of handlers to get tm hierarchy internals
Date: Sat, 18 Sep 2021 10:31:56 -0400	[thread overview]
Message-ID: <1631975519-30924-7-git-send-email-skoteshwar@marvell.com> (raw)
In-Reply-To: <1631975519-30924-1-git-send-email-skoteshwar@marvell.com>

From: Satha Rao <skoteshwar@marvell.com>

Platform specific TM tree hierarchy details are part of common cnxk
driver. This patch introduces missing HAL apis to return state of
TM hierarchy required to support ethdev TM operations inside cnxk PMD.
