Subject: [PATCH] MIPS: Lantiq: Keep ethernet enabled during boot
|
|
|
|
Disabling ethernet during reboot (only to enable it again when the
|
|
ethernet driver attaches) can put the chip into a faulty state where it
|
|
corrupts the header of all incoming packets.
|
|
|
|
This happens if packets arrive during the time window where the core is
|
|
disabled, and it can be easily reproduced by rebooting while sending a
|
|
flood ping to the broadcast address.
