Genet doesn't send/recieve when config_hz is set lower than 100 Hz

[mrwizardwizard]

Describe the bug

Genet doesn't send/receive when config_hz is set lower than 100 Hz (using a custom timer frequency) on raspberry Pi 4 model B

Setting a custom timer value is located in kernel/Kconfig.hz

it can be set as low as 16 Hz

Steps to reproduce the behaviour

Change Kconfig.hz located in kernel/Kconfig.hz and add/change

choice prompt "Timer frequency" default HZ_16 help

config HZ_16 bool "16 HZ" help

endchoice

config HZ int default 16 if HZ_16

config SCHED_HRTICK def_bool HIGH_RES_TIMERS

recompile the kernel, boot it, and genet won't send/receive properly.

Are you saying that 99Hz doesn't work?

I tried 16Hz and 50Hz and genet doesn't seem to work correctly, only works on 100Hz and above, didn't try 99Hz lol, but it is some kind of bug because with raspberry pi 3 model B+, i was able to use any Hz lower than 100Hz, like 16Hz.
