Subject: [PATCH net-next 19/19] r8169: remove jumbo_tx_csum from chip config
struct
According to the chip configuration entries only RTL8169 (ver <= 06)
supports tx checksumming for jumbo packets.
By the way: constant JUMBO_1K is a little misleading because it refers
to the standard packet size and not to a jumbo packet size.
By implementing this rule we can get rid of configuring tx checksumming
support per chip type.
