Subject: Enable e1000 as entropy source (disabled by default)
|
|
References: FATE#307517
|
|
Patch-mainline: never
|
|
|
|
Based on the patch by Oracle:
|
|
|
|
> e1000: Add IRQF_SAMPLE_RANDOM flag to e1000 as a module option
|
|
>
|
|
> This patch allows for the bnx2 to add to the /dev/random entropy pool
|
|
> via a module parameter, entropy.
|
|
>
|
|
> 0 - default for EL5 - do not populate the entropy pool
|
|
> 1 - optional - Uses IRQF_SAMPLE_RANDOM flag on request_irq calls to populate
|
|
> the /dev/random pool
