How to check that the patch will fit the updated kernel sources?

Question

linux

After the next system update, the network card stopped working. Got a kernel patch.
How to check that the patch will fit the updated kernel sources.
Which command to check if the patch will be applied to the sources:

patch --dry-run
patch --applicable
patch --unified
patch -pl
patch --context

Answer 1

The patch contains relative paths to files and must be applied in a specific directory. This should normally be the root directory of the project, but the patch contains 1 level more directories. The extra level is truncated with the -p1 option. This is a unit, not a lowercase l, as you wrote.
patch -p1 --dry-run < patch
