Description
In the Linux kernel, the following vulnerability has been resolved:
octeontx2-af: Block VFs from clobbering special CGX PKIND state
PF and VF NIX LFs that share a CGX LMAC reuse the same hardware PKIND
programming. When HiGig2 or EDSA parsing is enabled, a VF NIX LF alloc must
not reset the LMAC RX PKIND or default TX parse config over the PF setup.
Add cgx_get_pkind() and rvu_cgx_is_pkind_config_permitted() so VFs skip
cgx_set_pkind(), rvu_npc_set_pkind(), and NIX_AF_LFX_TX_PARSE_CFG updates
when the LMAC is using NPC_RX_HIGIG_PKIND or NPC_RX_EDSA_PKIND.
