bnx2x: Create separate folder for bnx2x driver
This commit includes files movement to newly created folder using git-mv command and fixes references in cnic and bnx2x code to each other. files moved using following: #!/bin/bash mkdir drivers/net/bnx2x/ list=$(cd drivers/net/ && ls bnx2x*.[ch]) for f in $list; do git mv -f drivers/net/$f drivers/net/bnx2x/$f done Signed-off-by: Dmitry Kravkov <dmitry@broadcom.com> Signed-off-by: Eilon Greenstein <eilong@broadcom.com> Signed-off-by: David S.
