From: Aleksander Jan Bajkowski Date: Tue, 1 Oct 2024 18:49:55 +0000 (+0200) Subject: lantiq: backport latest upstream patches X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=5ca8a4a03a0a06ee3ed6f0f7d48e059de420710e;p=openwrt%2Fstaging%2Fansuel.git lantiq: backport latest upstream patches Backport patch that fixes memory disclosure in packet padding. The downstream driver supports statistics, so when a packet cannot be padded the statistics of dropped packets are incremented. The other patches do not introduce any functional changes.
