Agenda items for next meeting (Aug 12th):
 - standalone phylink PCS drivers: as part of phylink? or as standalone
   subsystem? or not at all?

Meeting notes
DPLL
 - Arkadiusz: The standalone DPLL driver from Ivan doesn't have a
   unique clock ID, which is supposed to be the handle for the whole DPLL
   devices. The clock ID works for time appliances. The standalone DPLL
   device doesn't have a network card, so no MAC address, or ID.
 - Ivan: the device can be connected to multiple controllers, and drive
   multiple clocks. There’s no ID on the device, no serial even. We use
   a random number for now, devlink can be used to change it.
 - Andrew: it’s an i2c device? (yes, i2c or SPI) Can we use the address?
 - Ivan: yes, but the i2c address is static, so if there are multiple
   buses or a mux the address will be the same for all devices in the
   system.
 - Andrew: we can include the full bus address (with the bus).
 - Jakub: can we define the relationship to the netdev port in the DT?
 - Ivan: we could extend the DT note which contains the pins to include the MAC phandle.
 - Andrew: you can use the DSA definition as the sample to steal ideas from.
 - Ivan: the DPLL can drive multiple NICs, which device to pick for the clock ID.
 - Andrew: a diagram will be very helpful; Jakub: prefer using an explicit annotation.
Next step: send an RFC to the DT list..



We also had a netdev foundation TSC meeting today, here are the notes:

CI migration / HW lab:
 - Simon: we sent the RFQ out, colo is 10-15k, managed solution is
   double that at least, last minute we got an offer to host the lab
   for free.
 - Andrew: having a commitment for the free offer for at least a year
   would be good
 - Johannes: the company is considering joining the Governing Board
   too, so they should stick around
 - Eric: what is the location?
 - Simon: Chicago and Amsterdam, none of them have our people local
The HW lab project ($70k regardless of colo selection) is approved for
funding.

Small budget items (<$1k/yr total - Google Drive, Plausible subscription):
 - Pay for a Google Drive for TSC docs and Plausible for web analytics
Approved

New members:
 - The company trying to join made us realize we don't have a process defined.
 - There may be contentious applications in future, do we want some control?
 - We have a voting system for electing TSC members, but not to Governing Board.
Revisit in next meeting.

Rate / rank other projects on GH:
 - We need a shepherd per project first - assign tickets in github
 - TSC members to "like" projects they want to see done
 - Johannes to add more labels/milestones to mark what's already in progress
Revisit in next meeting.

How do we engage with the Governing Board:
 - Simon: the GB has a chair elected. Whenever we have a proposal we
   contact the chair and ask for them to convene.
 - Willem: does the board has a regular meeting?
 - Simon: the cadence is not decided, the default is every 3mo. We can
   ask to expedite, or even to meet monthly.
 - Willem: if we’re trying to get them to convene we should ask about
   the membership vote right now. Avoid delays.
 - Ask LF if membership approval is allowed. Ask for simple majority vote.
 - Simon: LF will be involved in the email exchange with GB, we can go
   direct to GB. Probably want a ⅔ majority, simple majority is too
   weak, veto is too strong.
 - Jakub: what about renewals. How about also optional ⅔ vote to block renewals,
   if no vote requested renewals auto-approved.
Ask the board for: HW lab, small items, and the membership vote amendment.
