[Intel-wired-lan] [PATCH S40 v3 4/15] ice: Add support for tunnel offloads
Tony Nguyen
anthony.l.nguyen at intel.com
Wed May 6 16:32:30 UTC 2020
Create a boost TCAM entry for each tunnel port in order to get a tunnel
PTYPE. Update netdev feature flags and implement the appropriate logic to
get and set values for hardware offloads.

---
v3:
- Removed unnecessary locking
v2:
- Add reference counting for same port additions
- Removed parameter 'index' from ice_tunnel_port_in_use()
- Change message level for exceeding max tunnel ports and tunnel not found to
info
- Redo description for ice_create_tunnel()
- Removed unneccesary casts
