Subject: [PATCH v2 1/1] solos-pci: Fix regression introduced by newest firmware
Date: Sun, 20 Mar 2011 18:52:15 -0700	[thread overview]
Message-ID: <4D86AF4F.5010203@redfish-solutions.com> (raw)

The newest FPGA firmware on the Solos processors correctly signals carrier transitions, bitrate, etc.

The driver previously ignored these messages, and the physical state was always ATM_PHY_SIG_UNKNOWN.

Now that the board reports its state, we expose a bug whereby the transition from UNKNOWN to LOST causes us to release all VC's.

We don't delete any VC's, but instead just send an indication of carrier change.
