However, the mac address can also be stored as a +different property or read from e.g. an mtd device. + +Create this node when reading a mac-address from OF if it does not +already exist and copy the mac-address used for the device to this +property. This way, the MAC address can be accessed using procfs. + +--- + net/core/of_net.c | 22 ++++++++++++++++++++++ + 1 file changed, 22 insertions(+) + +diff --git a/net/core/of_net.c b/net/core/of_net.c +index 71c38b532f72..43b28c8ddff9 100644 --- a/net/core/of_net.c +++ b/net/core/of_net.c -@@ -95,6 +95,27 @@ static int of_get_mac_addr_nvmem(struct +@@ -95,6 +95,27 @@ static int of_get_mac_addr_nvmem(struct device_node *np, u8 *addr) return 0; } @@ -28,7 +47,7 @@ /** * of_get_mac_address() * @np: Caller's Device Node -@@ -175,6 +196,7 @@ found: +@@ -175,6 +196,7 @@ int of_get_mac_address(struct device_node *np, u8 *addr) addr[5] = (mac_val >> 0) & 0xff; } @@ -36,3 +55,5 @@ return ret; } EXPORT_SYMBOL(of_get_mac_address); +-- + |
