[j-nsp] Rate selectability on MPC7E-MRATE

[sthaug at nethelp.no]

> 2. If you put a 100G optic in the QSFP28 port, the other 2 QSFP ports are not available. So 100G per group with a QSFP28 in them. Assuming only 100G QSFPs in use, the card will do 400G total.

Yes. But you can have 8 x 10G in addition in the form of 2 x 40G with
breakout. This is from one of our routers with an MPC7E-MRATE card:

xe-3/0/0:0              down  down
xe-3/0/0:1              down  down
xe-3/0/0:2              down  down
xe-3/0/0:3              down  down
et-3/0/2                up    up
et-3/0/5                up    up
xe-3/1/0:0              down  down
xe-3/1/0:1              down  down
xe-3/1/0:2              down  down
xe-3/1/0:3              down  down
et-3/1/2                up    up
et-3/1/5                up    down

and the corresponding chassis config is:

pic 0 {
    port 0 {
        speed 10g;
    }
    port 2 {
        speed 100g;
    }
    port 5 {
        speed 100g;
    }
}
pic 1 {
    port 0 {
        speed 10g;
    }
    port 2 {
        speed 100g;
    }
    port 5 {
        speed 100g;
    }
}
