stable inclusion from stable-v5.10.99 commit 75bbda318987975905ad159c0bf30a350f847f49 bugzilla: https://gitee.com/openeuler/kernel/issues/I55O7H
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=...
--------------------------------
commit 1293fccc9e892712d910ec96079d3717307f1d2d upstream.
Drivers are expected to set the PHY current_channel and current_page according to their default state. The hwsim driver is advertising being configured on channel 13 by default but that is not reflected in its own internal pib structure. In order to ensure that this driver consider the current channel as being 13 internally, we at least need to set the pib->channel field to 13.
