Subject: net: hns: make arrays static, makes object smaller
Patch-mainline: v5.5-rc1
Git-commit: 99d895729f5d438518c8223d7ce81615cb9a88e9
References: bsc#1154353
Don't populate the arrays port_map and sl_map on the stack but
instead make them static. Makes the object code smaller by 64 bytes.
Before:
text data bss dec hex filename
49575 6872 64 56511 dcbf hisilicon/hns/hns_dsaf_main.o
After:
text data bss dec hex filename
49350 7032 64 56446 dc7e hisilicon/hns/hns_dsaf_main.o
(gcc version 9.2.1, amd64)
