From: Olliver Schinagl Date: Thu, 22 Sep 2022 10:05:00 +0000 (+0200) Subject: base-files: Do not break on non-eth ports X-Git-Tag: v23.05.0-rc1~289 X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=3da70c64697aa6ebe4e81b162523d68fcff97b32;p=openwrt%2Fstaging%2Fpepe2k.git base-files: Do not break on non-eth ports When using OpenWRT with DSA and 'lan' ports, we could get an empty `next_eth`. This is of course not desirable, as this causes `sh: out of range` errors when trying to determine which one would be greater. It turns out, that we don't even need this check at all because, when looking for all existin eth*s on a system, and take the highest index and then iterate a set of devices and rename to eth${highest_index+n}, it is guaranteed that there will be no conflict.
