Add a module parameter radios to allow users to configure the number of virtual radios created by mac802154_hwsim at module load time. This replaces the previously hardcoded value of 2. * Added a new module parameter radios * Modified the loop in hwsim_probe() * Updated log message in hwsim_probe() Signed-off-by: Ramon Fontes <redacted> --- drivers/net/ieee802154/mac802154_hwsim.c | 11 ++++++++--- 1 file changed, 8 insertions(+), 3 deletions(-)
