[PATCH v3 0/2] staging: rtl8723bs: Cleanups for rtw_xmit.c

[Marcos Andrade]

This patch series cleans up rtw_xmit.c by replacing magic numbers with
proper macros and updating the sleep API, as suggested by reviewers.

Patch 1 replaces network magic numbers with EtherType macros.
Patch 2 updates an msleep() call to the new fsleep() API.

Changes in v3:
 - Grouped the patches into a series because patch 2 depends on the 
   include context of patch 1.

[PATCH v3 1/2] 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.

[PATCH v3 2/2] staging: rtl8723bs: Replace msleep() with fsleep()

[Marcos Andrade]

Replace msleep(10) with fsleep(10 * USEC_PER_MSEC) in _rtw_init_xmit_priv().
fsleep() is the new standard API for delays, as it automatically chooses
the best sleep method based on the duration.

#6:
Replace msleep(10) with fsleep(10 * USEC_PER_MSEC) in _rtw_init_xmit_priv().

Remember to always run "./scripts/checkpatch.pl --strict <patch>" before
sending a patch off to catch things like this.

Thanks,
