Subject: [PATCH] net: 3com: typhoon: fix typhoon_get_link_ksettings

When moving from typhoon_get_settings to typhoon_getlink_ksettings
in the commit commit f7a5537cd2a5 ("net: 3com: typhoon: use new api
ethtool_{get|set}_link_ksettings"), we use a local variable supported
but we forgot to update the struct ethtool_link_ksettings with
this value.

We also initialize advertising to zero, because otherwise it may
be uninitialized if no case of the switch (tp->xcvr_select) is used.

One "commit" is enough. :-)
