my $hashref = \$devstats->{$nic};
$hashref = \$$hashref->{$_} for @data[5..$#data];
$$hashref = $value;
should be
my $scalarref = \$devstats->{$nic};
$scalarref = \$$scalarref->{$_} for @data[5..$#data];
$$scalarref = $value;
This can be simplified to
my $scalarref = \$devstats;
$scalarref = \$$scalarref->{$_} for $nic, @data[5..$#data];
$$scalarref = $value;
or
my $scalarref = \$devstats;
$scalarref = \$$scalarref->{$_} for @data[4..$#data];
$$scalarref = $value;
This can be replaced with
sub dive_val :lvalue { my $p = \shift; $p = \$$p->{$_} for @_; $p }
dive_val($devstats, @data[4..$#data]) = $value;
or
use Data::Diver qw( DiveVal );
DiveVal($devstats //= {}, map \$_, @data[4..$#data]) = $value;
How these work is explained here.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
