Subject: [PATCH 3.18 47/56] net: usb: rtl8150: demote allmulti message to dev_dbg()

3.18-stable review patch.  If anyone has any objections, please let me know.

------------------

From: David Lechner <david@...hnology.com>

[ Upstream commit 3a9b0455062ffb9d2f6cd4473a76e3456f318c9f ]

This driver can spam the kernel log with multiple messages of:

    net eth0: eth0: allmulti set

Usually 4 or 8 at a time (probably because of using ConnMan).

This message doesn't seem useful, so let's demote it from dev_info()
to dev_dbg().
