Hi @kperumalbfn , do we still need this change? Looks like we are going to stick on the 10 UC queue now.

[kperumalbfn]

@r12f According to Broadcom, this bcm config file supports only 8 UCs. So, we can modify once we get full 10 UC queue support.

[r12f]

I see. That sounds good!

[r12f]

Basically, we will update all the bcm configs again once we get the 10 UC Q supports, am I right? @kperumalbfn
