Subject: [net PATCH v2 0/9] Macsec fixes for CN10KB

This patch set has fixes for the issues encountered while
testing macsec on CN10KB silicon. Below is the description
of patches:

Patch 1: For each LMAC two MCSX_MCS_TOP_SLAVE_CHANNEL_CFG registers exist
	 in CN10KB. Bypass has to be disabled in two registers.

Patch 2: Add workaround for errata w.r.t accessing TCAM DATA and MASK registers.

Patch 3: Fixes the parser configuration to allow PTP traffic.

Patch 4: Addresses the IP vector and block level interrupt mask changes.
 
Patch 5: Fix NULL pointer crashes when rebooting

Patch 6: Since MCS is global block shared by all LMACS the TCAM match
	 must include macsec DMAC also to distinguish each macsec interface

Patch 7: Before freeing MCS hardware resource to AF clear the stats also.

Patch 8: Stats which share single counter in hardware are tracked in software.
	 This tracking was based on wrong secy mode params.
	 Use correct secy mode params

Patch 9: When updating secy mode params, PN number was also reset to
	 initial values. Hence do not write to PN value register when
	 updating secy.


Geetha sowjanya (3):
  octeonxt2-af: mcs: Fix per port bypass config
  octeontx2-af: mcs: Config parser to skip 8B header
  octeontx2-af: mcs: Fix MCS block interrupt  

Subbaraya Sundeep (6):
  octeontx2-af: mcs: Write TCAM_DATA and TCAM_MASK registers at once
  octeontx2-pf: mcs: Fix NULL pointer dereferences
  octeontx2-pf: mcs: Match macsec ethertype along with DMAC
  octeontx2-pf: mcs: Clear stats before freeing resource
  octeontx2-pf: mcs: Fix shared counters logic
  octeontx2-pf: mcs: Do not reset PN when updating secy
