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: [email protected]
Reporter: [email protected]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.
