[Bridge] setting STP values via brctl
...TIME);
}
Note the tv_to_jiffies() call.
Then, I looked in the kernel file linux/net/bridge/br_sysfs_br.c at
the following function:
static void set_hello_time(struct net_bridge *br, unsigned long val)
{
unsigned long t = clock_t_to_jiffies(val);
br->hello_time = t;
if (br_is_root_bridge(br))
br->bridge_hello_time = t;
}
Note the clock_t_to_jiffies() call.
Are we converting the time in brctl to jiffies and then when it enters
the kernel, we again change the value again to jiffies?
Or have I misses something completely?

[Bridge] [BRIDGE] Unaligned access on IA64 when comparing ethernet addresses
From: Evgeny Kravtsunov <emkravts@openvz.org>
compare_ether_addr() implicitly requires that the addresses
passed are 2-bytes aligned in memory.
This is not true for br_stp_change_bridge_id() and
br_stp_recalculate_bridge_id() in which one of the addresses
is unsigned char *, and thus may not be 2-bytes aligned.
