tc_core.c: |
| 26 |
As kernel part of things relies on cell align which is always set to -1, |
| 27 |
I also added it to userspace computation stage. This way if someone |
| 28 |
specified e.g. 2048 and 512 for mtu and tsize respectively, one wouldn't |
| 29 |
end with tsize supporting mtu 4096 suddenly, New default mtu is also set |
| 30 |
to 2048 (disregarding weirdness of setting mtu to such values). |
| 31 |
|
| 32 |
|
| 33 |
Unless I missed something, this is harmless and feels cleaner, but if it's |
| 34 |
not allowed, documentation will have to be changed back to 2047 + extra |
| 35 |
explanation as well. |
