Before this patch, many warnings like below were generated
during compilation with ArmCC
[Warning] lwip_ethernet.h@57,0: #3135-D: attribute does not apply to any entity
This happens here as ``--gnu`` option of ArmCC is being used, which
enables the GNU compiler extensions that the ARM compiler supports.
This is solve by adding a extra check on __CCARM .
In case of sequential transmit / receive, there is a need to:
- not use the reload option
- generate a new START on each new transaction
This applies to all HAL supporting the IP version V2.
