| Subject: [PATCH] net: fib_rules: Correctly set table field when table number |
| exceeds 8 bits |
| |
| commit 540e585a79e9d643ede077b73bcc7aa2d7b4d919 upstream. |
| |
| In 709772e6e06564ed94ba740de70185ac3d792773, RT_TABLE_COMPAT was added to |
| allow legacy software to deal with routing table numbers >= 256, but the |
| same change to FIB rule queries was overlooked. |
