[hobbit] ifstat and e1000g Ethernet driver

[Eric Meddaugh]

Found the problem, tested and fixed it on our Hobbit install.  In the
do_ifstat.c file, change:

static const char *ifstat_solaris_exprs[] = {
        "^[a-z]+:\\d+:([a-z0-9]+):obytes64\\s+(\\d+)",
        "^[a-z]+:\\d+:([a-z0-9]+):rbytes64\\s+(\\d+)"
};

To this:

static const char *ifstat_solaris_exprs[] = {
        "^[a-z0-9]+:\\d+:([a-z0-9]+):obytes64\\s+(\\d+)",
        "^[a-z0-9]+:\\d+:([a-z0-9]+):rbytes64\\s+(\\d+)"
};


The problem is that, before hand all interfaces only had letters in them
as the base, "dmfe", "ce", "eri", "ge", "hme", etc...  The T2000 has
some even with "ipge", this works.  The "e1000g" does not.  The change
above allows the interface now to have letters and numbers in it.  You
just need to recompile and re-install.


Any way this code change can get into the base?  I didn't bother
providing a diff as it's quite a minor change.  This just affects the
ifstat_solaris_exprs.

Thanks.

The problem is not about active interfaces but about the name "e1000g0".
It 
will not be taked into account for creating a rrd file. This means there
is no 
ifstat.e1000g0.rrd and therefore no "Network Traffic" graph in the
trends.
