From: Tariq Toukan <tariqt@nvidia.com>
Date: 2024-07-29 12:45:45
Subsystem:
bonding driver, networking drivers, the rest · Maintainers:
Jay Vosburgh, Andrew Lunn, "David S. Miller", Eric Dumazet, Jakub Kicinski, Paolo Abeni, Linus Torvalds
From: Jianbo Liu <redacted>
Add this implementation for bonding, so hardware resources can be
freed after xfrm state is deleted.
Fixes: 9a5605505d9c ("bonding: Add struct bond_ipesc to manage SA")
