[PATCH 2/2] crypto: octeontx2: hardware configuration for inline IPsec

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



On OcteonTX2/OctoenTX3 variants of silicon, Admin function (AF)
handles resource allocation and configuration for PFs and their VFs.
PFs request the AF directly, via mailboxes.
Unlike PFs, VFs cannot send a mailbox request directly. A VF sends
mailbox messages to its parent PF, with which it shares a
mailbox region. The PF then forwards these messages to the AF.

This patch adds code to configure inline-IPsec HW resources for
CPT VFs as CPT VFs cannot send a mailbox request directly to AF.
