Murali Karicheri says: ==================== net: ti: netcp: restore get/set_pad_info() functionality This series fixes a regression and add some improvements for the ease of maintainance. Incorporated comments against v1. Changelogs: v2 : combined 2-3 into one patch as this involves a header change fixed a parse warning in 3/4 per comment from Arnd. Removed Sign-off from Arnd against 1/4 added comments in 3/3 to alert on the usage of sw data per review comments v1 : added 2-4 to accomodate feedback received from review v0 : initial version to fix the regression (From Grygorii) ==================== Signed-off-by: David S.
