Subject: i40e: Add define for interrupt name string len
X-Git-Tag: v4.0~334^2~193^2~12
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=b294ac70fcfa6b76defd9c2e3f2b28947a8a8d76;p=platform%2Fkernel%2Flinux-amlogic.git

i40e: Add define for interrupt name string len

This patch creates a define for interrupt name string configuration that
is large enough to contain full bus/slot info, rather than just netdev->name.
