-Subject: [PATCH] netfilter: nft_flow_offload: fix offload with pppoe +
- vlan
-
-When running a combination of PPPoE on top of a VLAN, we need to set
-info->outdev to the PPPoE device, otherwise PPPoE encap is skipped
-during software offload.

1. fix an crash bug at 'devs[dir] = xt_out(par)'. dir = CTINFO2DIR(ctinfo), it must before 'devs[dir] = xt_out(par)'. 2. not recommended use hardware offload if encaps >= 2 hardware cannot dispose (8021q+8021q+pppoe) L2 head. 3. already solved PPPoE header offset issue, so need remove 704-03-netfilter-nft_flow_offload-fix-offload-with-pppoe-vl.patch Signed-off-by: LiXiong Liu <lxliu@ikuai8.com> --- ...ft_flow_offload-fix-offload-with-pppoe-vl.patch | 24 ----- ...tfilter-xt_FLOWOFFLOAD-support-qinq-pppoe.patch | 107 +++++++++++++++++++++ 2 files changed, 107 insertions(+), 24 deletions(-) delete mode 100644 target/linux/generic/pending-5.10/704-03-netfilter-nft_flow_offload-fix-offload-with-pppoe-vl.patch create mode 100644 target/linux/generic/pending-5.10/706-04-netfilter-xt_FLOWOFFLOAD-support-qinq-pppoe.patch
