Driver: bnxt_en

[Eldho Paul Mathew]

Hi All,

What is the importance of the 'ice' driver?

Right now I am using 18.05.1. Does it have 'ice' driver support?

We bought a new card: BCM57508 NetXtreme-E 10Gb/25Gb/40Gb/50Gb/100Gb/200Gb
Ethernet

To support this card using the 'ice' driver, is the DPDK 18.05.1 version
sufficient, or is there any other driver that is the placeholder for 'ice'
in 18.05.1?

If I need to go for an upgrade, which is the minimum version to support
this card by 'ice'?

Kindly help!
