[Bridge] BRCTL is displaying only 32 bridge interfaces even /proc/net/dev is showing more then that
Hi All,
I am using Linux 2.6.15 kernel. I want to create 4094 bridge interface but I am
able to see only 32 bridge interfaces with the help of "brctl show". I
am able see other interfaces into /proc/net/dev but brctl is not showing more
then 32. It is also not allowing any operations (add/del) over those interfaces.
Is it correct behaviour or I have do some changes in some settings.?
Could anybody please help me in this??
With Regards

When interface changed to sysfs that was addressed.
