[PATCH net-next v3 0/5] net: centralize master device offload feature computation

[Hangbin Liu <liuhangbin@gmail.com>]

Currently, master devices (bonding, bridge, team) manually call
netdev_compute_master_upper_features() scattered throughout their port
add/remove operations. This approach requires each driver to remember
to update features at the right times and leads to code duplication.

The series adds a new ndo_update_offloads callback that is automatically
invoked during feature updates when upper/lower device relationships change.
This centralizes the feature computation flow and removes the burden
from individual drivers.

Changes in v3:
- ndo_set_features may be skipped when no feature change, fallback to
  use ndo_update_offloads for offload computation (Simon Horman)
- Link to v2: https://lore.kernel.org/r/20260313-offload_compute-v2-0-ffbc8ce5d50c@gmail.com

Changes in v2:
- Fix macsec Security Entity uninitialized issue (Sabrina Dubroca)
  - Tested with macsec-offload.sh, rtnetlink.sh, link_netns.py, all pssed
- Link to v1: https://lore.kernel.org/r/20260310-offload_compute-v1-0-3df79c09ea65@gmail.com

Hangbin Liu (5):
      net: add ndo_update_offloads for offload computation
      net: use ndo_update_offloads to set offload features for bonding/bridge/team
      macsec: move netdev_upper_dev_link() after macsec_changelink_common()
      failover: use ndo_update_offloads for failover offload compute
      net: no need to disable LRO specifically
