[dpdk-dev] [PATCH v2 0/2] remove some limitations and operations

[dpdk-dev] [PATCH v2 0/2] remove some limitations and operations

[Guoyang Zhou]

The maximum number of queues on the chip can be any value greater
than 0, it does not have to be the power of two, if it does not be
fixed, dpdk initialization may be failed with OVS mode firmware
and remove the operation of optical modules in the link function, because
when device binds from dpdk to kernel, it will be linked failed.

--
v1->v2:
  - add some necessary comments for patches
  - correct fixed patch id

v1:
  - remove the limitation for max queue num
  - remove the operation of optical modules in the link function

Guoyang Zhou (2):
  net/hinic/base: remove the limitation for max queue num
  net/hinic: remove the operation of optical modules

[dpdk-dev] [PATCH v2 2/2] net/hinic: remove the operation of optical modules

[Guoyang Zhou]

Remove the operation of optical modules in the link function, because
when device binds from dpdk to kernel, it will be linked failed. This
function does not take effect in cable mode, therefore, optimization
is required.

These last minute patches are fixing old issues
but you insisted to get them in DPDK 20.11.0. so they are applied.
