From f97d5c2a453e26071e3b0ec12161de57c4a237c4 Mon Sep 17 00:00:00 2001 From: Khalid Manaa Date: Tue, 19 May 2020 15:45:38 +0300 Subject: net/mlx5e: Add handle SHAMPO cqe support This patch adds the new CQE SHAMPO fields: - flush: indicates that we must close the current session and pass the SKB to the network stack. - match: indicates that the current packet matches the oppened session, the packet will be merge into the current SKB. - header_size: the size of the packet headers that written into the headers buffer. - header_entry_index: the entry index in the headers buffer. - data_offset: packets data offset in the WQE. Also new cqe handler is added to handle SHAMPO packets: - The new handler uses CQE SHAMPO fields to build the SKB. CQE's Flush and match fields are not used in this patch, packets are not merged in this patch.
