tohojo requested changes on this pull request.
This is a good start! There are some details to fix below. Also, you'll need to
add a proper commit message. The first line should be a oneline description of
the change, prefixed by the system you are touching (so something like
"metadata: Add parsing of WiFi status information". Then add a description of
what your change does (a shortish paragraph is probably enough for this
change), with an example of the output you are parsing embedded in the commit
message. You'll also need to add a Signed-off-by tag, as the bot says.
When revising, you can rewrite the commit in your local git tree, and
force-push it to the same branch; that will update this pull request directly,
while still keeping the history clean.
Feel free to ask clarifying questions, of course :)

You'll also need to add appropriate calls to this function in
record_metadata(); I'd suggest putting them along with the calls to
get_ip_addrs() and get_gateways()

This needs to discard empty lines first

Since you're doing the split here, better to use the 'k' and 'v' variables
further down instead of parts[0] and parts[1]

Please add a comment with an example of the line you are trying to parse with
this

Also, you'll need to handle unwanted lines. On my system, the output looks like
this:
```
Interface wlan0
ifindex 3
wdev 0x1
addr 98:de:ad:ca:fe:85
ssid myssid
type managed
wiphy 0
channel 36 (5180 MHz), width: 80 MHz, center1: 5210 MHz
txpower 22.00 dBm
multicast TXQ:
qsz-byt qsz-pkt flows drops marks overlmt hashcol
tx-bytestx-packets
0 0 0 0 0 0 0 0
0
```
Your parser will choke on the bit at the bottom; I think it's probably fine if
you just abort parsing when you get to the "multicast TXQ" line...
