Subject: net: fsl_enetc: Introduce enetc_dev_id()
X-Git-Tag: v2025.04-rc1~41^2~10
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=4eb5ef73a9565a78dd2a18d0ff4576701bedf872;p=pandora-u-boot.git

net: fsl_enetc: Introduce enetc_dev_id()

Introduce mapping function enetc_dev_id(), which converts PCIe BDF of
the ENETC into linear incrementing index usable e.g. as interface index.
This replaces the current ad-hoc calculation used in the code with a
dedicated function. No functional change.
