We are using DPDK 18.05.1

We received a new network card.

Broadcom Inc. and subsidiaries BCM57414 NetXtreme-E 10Gb/25Gb RDMA Ethernet
Controller

DPDK 18.05.1 has support for this card and driver bnxt_en?

If not, which stable version onwards has this driver support added?

Release 18.05 is not a stable LTS version.

Let me teach you how to look this question up.

To look up device you need the actual PCI-ID, using pcilookup.com
	14e4:16d7

Look at source of drivers/net/bnxt/bnxt_ethdev.c for the pci table bnxt_id_pci_map.
The entry for 16d7 is 
	#define BROADCOM_DEV_ID_57414		0x16d7

Using git blame find the commit that added that:

$ git blame drivers/net/bnxt/bnxt_ethdev.c | grep BROADCOM_DEV_ID_57414
3fab7694403 (Ajit Khaparde                   2017-04-26 14:20:02 -0500   51) 	{ RTE_PCI_DEVICE(PCI_VENDOR_ID_BROADCOM, BROADCOM_DEV_ID_57414_VF) },
1f4a84672ec (Ajit Khaparde                   2017-01-06 13:55:17 -0600   60) 	{ RTE_PCI_DEVICE(PCI_VENDOR_ID_BROADCOM, BROADCOM_DEV_ID_57414) },
1f4a84672ec (Ajit Khaparde                   2017-01-06 13:55:17 -0600   68) 	{ RTE_PCI_DEVICE(PCI_VENDOR_ID_BROADCOM, BROADCOM_DEV_ID_57414_MF) },
3f6d59b0c88 (Kalesh AP                       2019-12-02 09:48:07 +0530 4999) 	case BROADCOM_DEV_ID_57414_VF:

So we want 1f4a84672ec 

If you look at that commit with a tool like gitk it shows it happened way back in 17.02
And the card is listed in driver for 18.11

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!

ice driver will not work with the card you have listed. It is for an Intel NIC.
Support for BCM5708 was added in 2019 in the Broadcom bnxt PMD.
You can either use the 19.11 - an LTS version. But that is not
maintained anymore.
You can use the 22.11 release which is still maintained. Refer to the
DPDK roadmap
for EOL releases.
