From: Christian Lamparter Date: Sat, 9 Mar 2019 18:05:17 +0000 (+0100) Subject: ipq40xx: fix phy interrupt setting X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=784f2e73df750e79759a80b21e09094262359f80;p=openwrt%2Fstaging%2Fnbd.git ipq40xx: fix phy interrupt setting This patch fixes a problem that was discovered during DSA development. On the MR33, the link change events from the external AR8035-PHY would never make it to the qca8k driver. The issue turned out to be a misplaced memcpy that was copying over the zero-initialized irq table, when it should have been set to PHY_POLL. Hence this patch moves the memcpy after the array has been initialized.
