Revision ba9ad2af7019956b990ad654c56da5bac1e8b71b authored by Jean Delvare on 11 October 2016, 11:13:27 UTC, committed by Wolfram Sang on 25 October 2016, 10:00:01 UTC
Starting with the 8-Series/C220 PCH (Lynx Point), the SMBus controller includes a SPD EEPROM protection mechanism. Once the SPD Write Disable bit is set, only reads are allowed to slave addresses 0x50-0x57. However the legacy implementation of I2C Block Read since the ICH5 looks like a write, and is therefore blocked by the SPD protection mechanism. This causes the eeprom and at24 drivers to fail. So assume that I2C Block Read is implemented as an actual read on these chipsets. I tested it on my Q87 chipset and it seems to work just fine.

config VLAN_8021Q
tristate "802.1Q/802.1ad VLAN Support"
---help---
Select this and you will be able to create 802.1Q VLAN interfaces
on your Ethernet interfaces. 802.1Q VLAN supports almost
everything a regular Ethernet interface does, including
firewalling, bridging, and of course IP traffic. You will need
the 'ip' utility in order to effectively use VLANs.
See the VLAN web page for more information:
<http://www.candelatech.com/~greear/vlan.html>
To compile this code as a module, choose M here: the module
will be called 8021q.
If unsure, say N.
config VLAN_8021Q_GVRP
bool "GVRP (GARP VLAN Registration Protocol) support"
depends on VLAN_8021Q
select GARP
help
Select this to enable GVRP end-system support. GVRP is used for
automatic propagation of registered VLANs to switches.
If unsure, say N.
config VLAN_8021Q_MVRP
bool "MVRP (Multiple VLAN Registration Protocol) support"
depends on VLAN_8021Q
select MRP
help
Select this to enable MVRP end-system support. MVRP is used for
automatic propagation of registered VLANs to switches; it
supersedes GVRP and is not backwards-compatible.
If unsure, say N.
