Subject: Re: [PATCH net-next] net: marvell: mvpp2: clear flow control modes
 in 10G mode

From: Russell King <>
Date: Sat, 09 Feb 2019 16:06:51 +0000

> When mvpp2 configures the flow control modes in mvpp2_xlg_config() for
> 10G mode, it only ever set the flow control enable bits.  There is no
> mechanism to clear these bits, which means that userspace is unable to
> use standard APIs to disable flow control (the only way is to poke the
> register directly.)
> Fix the missing bit clearance to allow flow control to be disabled.
> This means that, by default, as there is no negotiation in 10G modes
> with mvpp2, flow control is now disabled rather than being rx-only.
