Subject: [PATCH] net: bcmgenet: Reset RBUF on first open
|
|
|
|
If the RBUF logic is not reset when the kernel starts then there
|
|
may be some data left over from any network boot loader. If the
|
|
64-byte packet headers are enabled then this can be fatal.
|
|
|
|
Extend bcmgenet_dma_disable to do perform the reset, but not when
|
|
called from bcmgenet_resume in order to preserve a wake packet.
|
|
|
|
N.B. This different handling of resume is just based on a hunch -
|
|
why else wouldn't one reset the RBUF as well as the TBUF? If this
|
|
isn't the case then it's easy to change the patch to make the RBUF
|
|
reset unconditional.
|
|
|
|
