[v6,0/5] drivers/net: add NXP ENETFEC driver

  This patch series introduce the enetfec driver, ENETFEC
(Fast Ethernet Controller) is a network poll mode driver for
the inbuilt NIC found in the NXP i.MX 8M Mini SoC.

An overview of the enetfec driver with probe and remove are in patch 1.
Patch 2 design UIO interface so that user space directly communicate with
a UIO based hardware device. UIO interface mmap the Control and Status
Registers (CSR) & BD memory in DPDK which is allocated in kernel and this
gives access to non-cacheble memory for BD.

Patch 3 adds the RX/TX queue configuration setup operations.
Patch 4 adds enqueue and dequeue support. Also adds some basic features
like promiscuous enable, basic stats.
Patch 5 adds checksum and VLAN features.

Hi Apeksha,

I have requested for techboard approval on uio part, comparing
having a new bus implementation.

Meanwhile I put some comments on the driver, but initially
it doesn't compile with latest DPDK.

Can you please send a new version that fixes the build error first,
so more checks can be done, later you can continue with other
comments in another version.


Thanks,
