net: mana: select PAGE_POOL
[ Upstream commit 340943fbff3d8faa44d2223ca04917df28786a07 ]
Mana uses PAGE_POOL API. x86_64 defconfig doesn't select it:
ld: vmlinux.o: in function `mana_create_page_pool.isra.0':
mana_en.c:(.text+0x9ae36f): undefined reference to `page_pool_create'
ld: vmlinux.o: in function `mana_get_rxfrag':
mana_en.c:(.text+0x9afed1): undefined reference to `page_pool_alloc_pages'
make[3]: *** [/home/yury/work/linux/scripts/Makefile.vmlinux:37: vmlinux] Error 1
make[2]: *** [/home/yury/work/linux/Makefile:1154: vmlinux] Error 2
make[1]: *** [/home/yury/work/linux/Makefile:234: __sub-make] Error 2
make[1]: Leaving directory '/home/yury/work/build-linux-x86_64'
make: *** [Makefile:234: __sub-make] Error 2
So we need to select it explicitly.
