octeontx2-af: Workarounds for HW errata
Errata 35038 Software sets NIX_AF_RX_SW_SYNC[ENA] to sync (flush) in-flight packets the RX data path before configuration changes (e.g. disabling one or more RQs). Hardware clears [ENA] to indicate sync is done An issue exists whereby NIX may clear NIX_AF_RX_SW_SYNC [ENA] too early. Errata 35057 NIX may corrupt internal state when conditional clocks turn off. So turnon all clocks by default. Errata 35786 Parse nibble enable NPC configuration for KEY generation has to be identical for both Rx and Tx interfaces. Also corrected endianness configuration for NIX i.e NIX_AF_CFG[AF_BE] is bit8 and not bit1.
