[PATCH v2 2/2] net: xilinx_axi: check PCS/PMA PHY status in setup_phy

Both PCS/PMA PHY and the external PHY need to have a valid link status in order to have Ethernet traffic. Check and wait this status at setup_phy() so that we could diagnose if there is a PHY issue. Signed-off-by: Andy Chiu Reviewed-by: Greentime Hu --- drivers/net/xilinx_axi_emac.c | 44

[PATCH 0/2] Manage PCS/PMA PHY if pressent

If both PCS/PMA PHY and an external PHY are pressent on the Ethernet, then the real link status should point to the external facing PHY. At the same time, we must ensure the link status of the PCS/PMA PHY is good before transmitting packets. Andy Chiu (2): net:xilinx_axi: add PCS/PMA PHY

[PATCH] net: xilinx: fix the wrong dma base address issue

use fdtdec_get_addr_size_auto_parent() to get correct base address. After applying this patch, we can get the correct base address of dma by replacing fdtdec_get_addr_size_fixed() with fdtdec_get_addr_size_auto_parent(). fdtdec_get_addr_size_auto_parent: na=1, ns=1, fdtdec_get_addr_size_fixed:

[PATCH 1/3] net: xilinx: fix load access fault

From: Greentime Hu phy_connect() may fail by returning a NULL pointer. Thus, axiemac_phy_init() should handle the case or we may get an access fault when it tries to dereference it. Signed-off-by: Greentime Hu Reviewed-by: Andy Chiu Signed-off-by: Andy Chiu --- drivers/net
