From b421909ce7c42109ebb3236275793b1c7fd3394e Mon Sep 17 00:00:00 2001 From: Bruce Richardson Date: Wed, 16 Mar 2022 13:45:44 +0000 Subject: [PATCH] doc: fix missing note on UIO module in Linux guide The docs on binding drivers was updated as part of the removal of the igb_uio module from the main DPDK repo. As part of that update, a note about uio_pci_generic requiring legacy interrupts was removed, but should have been kept.
