Dell R740 running ESXi 8 did not detect Broadcom BCM5720

Hello,

My R740 has Broadcom 57412 Dual Port 10GbE SFP+ & 5720 Dual Port 1GeE BASE-T rNDC . (2 NICs 57412 and 2 NICs 5720). I installed ESXi v8u2. Everything worked fine. ESX detected all 4 NICs.

After i installed iSCSI Adapter, and successfully attached the R740 to my PowerVaul ME5012, through switches, i lost the 2 NICs 5720. ESX did not detects the 5720 NICs. However, the 2 57412 NICs works fine.
