| Subject: [PATCH] hv_netvsc: flag software created hash value |
| |
| commit df9f540ca74297a84bafacfa197e9347b20beea5 upstream. |
| |
| When the driver needs to create a hash value because it |
| was not done at higher level, then the hash should be marked |
| as a software not hardware hash. |
| |
| Fixes: f72860afa2e3 ("hv_netvsc: Exclude non-TCP port numbers from vRSS hashing") |
