Subject: efi_loader: efi_net: hwaddr_size = 6
X-Git-Url: http://git.dujemihanovic.xyz/img/sics.gif?a=commitdiff_plain;h=5d4a5ea964e523a29ec077b6f95537956c366c1f;p=u-boot.git

efi_loader: efi_net: hwaddr_size = 6

The length of a MAC address is 6.
We have to set this length in the EFI_SIMPLE_NETWORK_MODE
structure of the EFI_SIMPLE_NETWORK_PROTOCOL.

Without this patch iPXE fails to initialize the network with
error message
SNP MAC(001e0633bcbf,0x0) has invalid hardware address length 0
