[elrepo] mac802154_hwsim kmod request

[Tamas Csirszka]

Hi Alan,

This is looking very good on el7 now.

[root at kernel7 ~]# uname -a
Linux kernel7 5.8.6-2.el7.elrepo.x86_64 #1 SMP Thu Sep 3 11:33:31 EDT 2020
x86_64 x86_64 x86_64 GNU/Linux
[root at kernel7 ~]# modinfo mac802154_hwsim
filename:
/lib/modules/5.8.6-2.el7.elrepo.x86_64/kernel/drivers/net/ieee802154/mac802154_hwsim.ko
license:        GPL
description:    Software simulator of IEEE 802.15.4 radio(s) for mac802154
srcversion:     E4B7E19C5975B465FEDCF0B
depends:        mac802154
retpoline:      Y

name:           mac802154_hwsim
vermagic:       5.8.6-2.el7.elrepo.x86_64 SMP mod_unload modversions
[root at kernel7 ~]# modprobe mac802154_hwsim
[root at kernel7 ~]# lsmod |grep mac802154_hwsim
mac802154_hwsim        24576  0
mac802154              86016  1 mac802154_hwsim
[root at kernel7 ~]#

Same time el8 hasn't changed, the whole ieee802154 folder content is
missing.

I'll engage the user and ask him to do some functional testing on el7, but
being able to list and load it on el7 without errors seems very promising.
Thank you!



Cheers,
Tamas
