Subject: Re: [PATCH net v2] net: usb: Remove disruptive netif_wake_queue in rtl8150_set_multicast

Hi Jakub,

I found the topic very interesting. So I looked into the existing drivers and almost all of them seem to be using `usb_submit_urb`s except `lan78xx` and `smsc75xx`, which have a work item to do the configuration. But I see no synchronization between their work and the data that is used to do the configuration (which can involve multiple requests to the device). Is there any synchronization that I am missing here? 

Thanks,
Deepak Sharma
