Subject: [PATCH ipsec v3 0/2] xfrm: Correct inner packet family determination

This series contains two 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.

V3:
 - Change xfrm_ip2inner_mode for the sel family specified

V2:
 - The original first patch was sent separately to "ipsec-next"

Jianbo Liu (2):
  xfrm: Check inner packet family directly from skb_dst
  xfrm: Determine inner GSO type from packet inner protocol
