[PATCH 1/2] staging: octeon: avoid void pointer arithmetic in ethernet-rx.c

[Oscar Alejandro Sánchez Lucero via B4 Relay]

From: Oscar Alejandro Sánchez Lucero <aleszlucero@xxxxxxxxx>

Arithmetic on void pointers is a non-standard GCC extension and
triggers -Wpointer-arith warnings. Cast the buffer pointer
returned by cvm_oct_get_buffer_ptr() to u8 * before subtracting
the offset.
