Subject: [PATCH net-next 0/3] xfrm: Correct inner packet family determination

This series contains three patches addressing issues in the XFRM
subsystem where the code incorrectly relied on static family fields
from the xfrm_state instead of determining the family from the actual
packet being processed. 

This was particularly problematic in tunnel mode scenarios when using
states that could handle different inner families.

Jianbo Liu (3):
  xfrm: Remove redundant state inner mode check
  xfrm: Check inner packet family directly from skb_dst
  xfrm: Determine inner GSO type from packet inner protocol
