5 years agonet/ena: remove lcore constraint from max queue number

net/ena: remove lcore constraint from max queue number

The number of queues was limited by number of lcores in the recent ENAv2
patch. However, some apps like symmetric_mp, are configuring multiple
queues although there is only single lcore used.

To prevent failure in that case, the lcore number constraint was
removed.

net/mlx5: fix VXLAN port registration race condition

E-Switch VXLAN tunneling rules require virtual VXLAN network
devices be created. These devices are managed by MLX5 PMD and
created/deleted dynamically.

Kernel creates the VXLAN devices and registers VXLAN UDP ports
to be hardware offloaded within the NIC kernel drivers. The
registration process is being performed into context of working
kernel thread and the race conditions might happen.

The VXLAN device is created and success code is returned to calling
application, but the UDP port registration process is not completed
yet and the next applied rule might be rejected by the driver with
ENOSUP code. This patch adds some timeout for new created devices,
allowing port registration process to be completed. The waiting
is performed once after device been created and first rule is being
applied.
