Subject: [PATCH] net: mcf: check receive buffer size register value
|
|
|
|
ColdFire Fast Ethernet Controller uses a receive buffer size
|
|
register(EMRBR) to hold maximum size of all receive buffers.
|
|
It is set by a user before any operation. If it was set to be
|
|
zero, ColdFire emulator would go into an infinite loop while
|
|
receiving data in mcf_fec_receive. Add check to avoid it.
