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(=3D204=
8),
should be: <=3D 256, >=3D 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.
