[PATCH net 3/3] net: mvneta: eliminate wrong call to handle rx descriptor error

[Gregory CLEMENT]

From: Yelena Krivosheev <yel...@marvell.com>

There are few reasons in mvneta_rx_swbm() function when received packet
is dropped. mvneta_rx_error() should be called only if error bit [16]
is set in rx descriptor.
