[PATCH] staging: rtl8723bs: Replace network magic numbers with EtherType macros

[Marcos Andrade]

Replace hardcoded magic numbers for network protocols (e.g., 0x0806
for ARP, 0x888e for EAPOL) with their standard EtherType macro
equivalents (ETH_P_ARP, ETH_P_PAE) defined in <linux/if_ether.h>.

This change improves code readability and aligns the driver with
standard Linux networking definitions.

You always include linux api headers with <> not "". Also, header files
should be included in alphabetical order:

>  #include <drv_types.h>
   #include <linux/if_ether.h>

You won't include <linux/delay.h> in your v2 for reasons below.

You didn't mention this in your changelog and is an unrelated change.
Please make this its own separate patch. Also, this should be changed
from msleep(10) to fsleep(10 * USEC_PER_MSEC) as this is the new
standard API.

Thanks,
