The first version of the driver had hard-coded the logic for handling the checksum offloading. This was designed according to the chips included in the STM platforms where: o MAC10/100 supports no COE at all. o GMAC fully supports RX/TX COE. This is not good for other chip configurations where, for example, the mac10/100 supports the tx csum in HW or when the GMAC has no IPC. Thanks to Johannes Stezenbach; he provided me a first draft of this patch that only reviewed the IPC for the GMAC devices. This patch also helps on SPEAr platforms where the MAC10/100 can perform the TX csum in HW. Thanks to Deepak SIKRI for his support on this. In the end, GMAC devices for STM platforms have a bugged Jumbo frame support that needs to have the Tx COE disabled for oversized frames (due to limited buffer sizes). This information is also passed through the driver's platform structure.
