If a NIC sees 11111110 (or something other than 8 ones) ) this is not a preamble so the frame is ignored. iphone xr charging time

"An Ethernet frame is preceded by a preamble and start frame delimiter (SFD), which are both part of the Ethernet packet at the physical layer. Each Ethernet frame starts with an Ethernet header, which contains destination and source MAC addresses as its first two fields.
