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
