Stijn Tintel 3a69ad3b2a kernel: split 82574L patch into multiple files
When refreshing patches that cointain multiple patches including headers
in a single file, quilt will remove the headers from all but the first
patch. This makes it difficult to review commits that refresh patches.
Next to that, if only a few of the patch series are accepted in -stable,
the patch needs to be manually modified. With each patch in a separate
file, it's just a matter of git rm.

Refresh patches while at it.

In case of error from e1e_rphy(), the loop will exit early and "success"
will be set to true erroneously.
