Subject: [PATCH v3] Create pci slot files for SMBIOS Type 9 entries
Date: Thu, 18 Feb 2016 20:40:32 +0000 [thread overview]
Message-ID: <1455827823254.98505@Dell.com> (raw)
The following diff builds on the "[PATCHv3] Save SMBIOS Type 9 System Slots"
This will create a /sys/bus/pci/slots/XXX file for each Type 9 entry. This will be \
used for systemd enumeration of NICs.
Only build if CONFIG_DMI is set
Signed-off-by: Jordan Hargrave <Jordan_Hargrave@dell.com>
