Hi John/Hyong Youb,
Not sure if you are monitoring dpdk bugzilla, but wanted to draw your
attention to https://bugs.dpdk.org/show_bug.cgi?id=1185
Maybe you have some clues about it and if we need to backport the
mentioned commit?
thanks,
Kevin.

Subject: [Bug 1185] enic: no longer accepting 2048 descriptor size in

Bug ID: 1185
Summary: enic: no longer accepting 2048 descriptor size in
20.11.6
Product: DPDK
Version: 20.11
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: normal
Priority: Normal
Component: core
Assignee: dev@dpdk.org
Reporter: ktray...@redhat.com
Target Milestone: ---
Hi enic maintainers,
With openvswitch 2.15 using dpdk 20.11.6, enic driver is reporting that it
cannot accept setup with default OVS number of tx descriptors (2048).
2022-08-19T16:29:38.555Z|00204|dpdk|ERR|Invalid value for nb_tx_desc(=2048),
should be: <= 256, >= 64, and a product of 32
OVS has used 2048 as default for many years and the code in 20.11.6 does not
look like it changed much from previous releases either.
The commit below [0] on dpdk main branch (but not on 20.11 branch),
changes how
max descriptor values are calculated.
So any idea why the 2048 can no longer be used with 20.11.6 ? some commit I
missed? different firmware?
or is it an incorrect calculation and the commit [0] is needed on stable
branches to correct this?
Thanks.

net/enic: support max descriptors allowed by adapter
Newer VIC adapters have the max number of supported RX and TX
descriptors in their configuration. Use these values as the
maximums.
