This patch set adds Xilinx AXI Multirate MAC(MRMAC) driver support.
This MRMAC is a high performance, low latency, adaptable Ethernet integrated hard IP. This can be configured up to four ports with MAC rates from 10GE to 100GE.
Supported Configuration Combinations: 1 × 100GE 2 × 50GE 1 × 40GE 4 × 25GE 4 × 10GE
Currently added support and tested below configurations in the driver: 4 × 25GE 4 × 10GE
Changes in v3:
- In V2 by mistake changed return type of isrxready() of xilinx_axi_emac driver instead of xilinx_axi_mrmac driver. Fixed it in V3.
Changes in v2:
- Changed all static allocations to dynamic and freed them.
- Used setbits_le32 and clrbits_le32 wherever applicable
- All return's are changed to proper error codes instead of 1 or -1
- Changed return type of isrxready() from int to bool
- Changed all printf's to log_warning, and debug to log_debug
- Added function headers with desciption
- Changed all capital hex numbers to small hex numbers
