net: sxgbe: add basic framework for Samsung 10Gb ethernet driver
This patch adds support for Samsung 10Gb ethernet driver(sxgbe). - sxgbe core initialization - Tx and Rx support - MDIO support - ISRs for Tx and Rx - ifconfig support to driver Signed-off-by: Siva Reddy Kallam <siva.kallam@samsung.com> Signed-off-by: Vipul Pandya <vipul.pandya@samsung.com> Signed-off-by: Girish K S <ks.giri@samsung.com> Neatening-by: Joe Perches <joe@perches.com> Signed-off-by: Byungho An <bh74.an@samsung.com> Signed-off-by: David S.
