Subject: net: bridge: convert MLDv2 Query MRC into msecs_to_jiffies for
max_delay
From: Daniel Borkmann <[email protected]>
[ Upstream commit 2d98c29b6fb3de44d9eaa73c09f9cf7209346383 ]
While looking into MLDv1/v2 code, I noticed that bridging code does
not convert it's max delay into jiffies for MLDv2 messages as we do
in core IPv6' multicast code.
RFC3810, 5.1.3. Maximum Response Code says:
The Maximum Response Code field specifies the maximum time allowed
before sending a responding Report. The actual time allowed, called
the Maximum Response Delay, is represented in units of milliseconds,
and is derived from the Maximum Response Code as follows: [...]
As we update timers that work with jiffies, we need to convert it.
