[PATCH] staging: rtl8723bs: remove header file ethernet.h

From: Michael Straube
Date: Wed Aug 25 2021 - 06:09:47 EST


The header file ehternet.h defines only two constants.

#define ETHERNET_HEADER_SIZE 14 /* Ethernet Header Length */
#define LLC_HEADER_SIZE 6 /* LLC Header Length */

Both are only used in the file core/rtw_recv.c and ETHERNET_HEADER_SIZE
just duplicates the in-kernel constant ETH_HLEN. Replace the usage of
ETHERNET_HEADER_SIZE with ETH_HLEN, move the definition of LLC_HEADER_SIZE
into rtw_rev.h (renamed to LLC_HEADER_LENGTH) and remove the now unused
header file ethernet.h.
