[Intel-wired-lan] How to update firmware?

[Paul Menzel]

Dear Linux folks,


How can I update the firmware of Intel network cards with free software 
utilities? Dell provides a binary to update the firmware, and it worked, 
but I’d like to have the sources. In this case, it was about the device 
below.

```
$ dmesg | grep igb
[…]
