lcs.64a3d7 `<bus ID of the LCS device>`: Allocating a socket buffer to interface `<network interface>` failed

Explanation
LAN channel station (LCS) devices require a socket buffer (SKB) structure
for storing incoming data. The LCS device driver failed to allocate an SKB
structure to the LCS device. A likely cause of this problem is memory
constraints.
User response
