Subject: eHEA: Fix bonding support
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=f9e29228e6f2058e7b086115ecb7008630ebd832;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

eHEA: Fix bonding support

The driver didn't allow an interface's MAC address to be modified if the
respective interface wasn't setup - a failing Hcall was the result. Thus
bonding wasn't usable. The fix moves the failing Hcall which was registering
a MAC address for the reception of BC packets in firmware from the port up
and down functions to the port resources setup functions. Additionally the
missing update of the last_rx member of the netdev structure was added.
