Changes in v4: None Changes in v3: -Move pfe_eth header files to include/net/pfe_eth -Use BIT macro wherever applicable
Changes in v2: -Add pfe_rx_done to clear bd after packet processing -remove unused code under CONFIG_UTIL_PE_DISABLED -Used BIT and GENMASK macros wherever applicable -Removed generic definitions that pollutes namespace -File names pfe.h renamed to pfe_hw.h to be more clear as it contains low level functions that directly access pfe hardware block -Added pfe_dm_eth.h for new driver model
