Два из четырех контроллеров ethernet отмечены как невостребованные после обновления до Ubuntu 20.04

Мой HP Server Blade имеет четыре сетевые карты, и они работали, как ожидалось, с Ubuntu 18.04. После обновления до Ubuntu 20.04 две из них отображаются как невостребованные. Все четыре из них от одного производителя Broadcom Inc; поэтому драйвер bnx2x должен быть одинаковым для всех них. Я также пробовал установить свежую ОС 20.04 на этот блейд с тем же результатом. Как установить драйвер для оставшихся двух контроллеров ethernet?
