Hi,
This patch series fixes a panic reported by syzkaller in the team/bond/gre
stacked non-Ethernet configuration:
https://syzkaller.appspot.com/bug?extid=3d8bc31c45e11450f24c
The first patch fixes the header_ops type confusion / parse recursion context
issue in team. The second patch adds a selftest to reproduce the reported
scenario and prevent regressions in the future.
Thanks.

Changes in v2:
- The same fix approach was applied to bonding first, but could cause
infinite recursion in bond_header_parse(). Eric spotted the issue and
fixed it in:
b7405dcf7385 ("bonding: prevent potential infinite loop in
bond_header_parse()")
After that fix landed, we continue with the same approach to fix team.
