Look for the Broadcom 57XX Driver_BACS combined package Driver Driver for PE 1950

We use 6 x Dell PE 1950 with "Broadcom BCM5708C NetXtreme II GigE" but we like to set up the teaming for NIC as for our Network redundancy (Red and Blue). PE 1950 is no longer supported by Dell and Information of the NIC drivers for PE 1950 in the Dell support are not clear. We look for a good information for the NIC driver for PE 1950 with "Broadcom BCM5708C NetXtreme II GigE" including NIC firmware.
