[dpdk-stable] [PATCH 4/9] net/ice/base: fix for memory handling

[Qi Zhang]

Fixed memory handling when memory allocated in user space was handled
as memory allocated in kernel space within QV os_dep implementation
of the ice_memdup function.

[dpdk-stable] [PATCH 8/9] net/ice/base: updated the add scheduler node counter

[Qi Zhang]

The number of nodes added counter was updated incorrectly. This issue
was exposed when the driver tried to add more than 128 queues per TC.

Fix added to update the counter correctly.
