	There is a number of different encapsulations for bridged setups, just pick the one relevant for your link:
		Connection: Bridged, VC/Mux RFC-1483/2684
		Protocol (bytes): Ethernet Header (14), ATM pad (2), ATM AAL5 SAR (8) : Total 24

		Connection: Bridged, VC/Mux+FCS RFC-1483/2684
		Protocol (bytes): Ethernet Header (14), Ethernet PAD [8] (0), Ethernet Checksum (4), ATM pad (2), ATM AAL5 SAR (8) : Total 28

		Connection: Bridged, LLC/SNAP RFC-1483/2684
		Protocol (bytes): Ethernet Header (14), ATM LLC (3), ATM SNAP (5), ATM pad (2), ATM AAL5 SAR (8) : Total 32
 
		Connection: Bridged, LLC/SNAP+FCS RFC-1483/2684
		Protocol (bytes): Ethernet Header (14), Ethernet PAD [8] (0), Ethernet Checksum (4), ATM LLC (3), ATM SNAP (5), ATM pad (2), ATM AAL5 SAR (8) : Total 36
To my knowledge, the worst case overhead for ADSL connections is 44bytes.

	If you do not have sufficient information about your encapsulation at hand contact me and I am happy to figure it our empirically...

	At least in Germany you can also find ADSL1 over ATM, but that has no bearing on the overhead or on the general ATM quantization issue. As fas as I know all ADSLs use an ATM carrier, while VDSL systems (hopefully) should use PTM (without the weird quantization issues).

Hope that helps

Once I restored a backup, everything was fine (NOTE: this is an assumption, it could have just been the additional reboot that fixed the flakeyness). The upgrade to 3.10.2 went quite smoothly for me. If I hit a problem with the upgrade to 3.10.3 I'll send a followup email.
