[ Upstream commit bbfc17e50ba2ed18dfef46b1c433d50a58566bf1 ]
bnxt_xdp_buff_init() does not modify the data_ptr or the len parameters, so no need to pass in the addresses of these parameters.
Fixes: b231c3f3414c ("bnxt: refactor bnxt_rx_xdp to separate xdp_init_buff/xdp_prepare_buff") Reviewed-by: Andy Gospodarek andrew.gospodarek@broadcom.com Reviewed-by: Somnath Kotur somnath.kotur@broadcom.com Reviewed-by: Pavan Chebbi pavan.chebbi@broadcom.com Signed-off-by: Michael Chan michael.chan@broadcom.com Signed-off-by: David S.
