This driver assigns PAGE_SIZE to a u16, which can't work when the page size is 256K. As reported by lkp:
drivers/net/vmxnet3/vmxnet3_drv.c: In function 'vmxnet3_rq_init': arch/powerpc/include/asm/page.h:24:20: warning: conversion from 'long unsigned int' to 'u16' changes value from '262144' to '0' drivers/net/vmxnet3/vmxnet3_drv.c:1784:29: note: in expansion of macro 'PAGE_SIZE' 1784 | rq->buf_info[0][i].len = PAGE_SIZE; ^~~~~~~~~
Simliar to what was done previously in commit fbdf0e28d061 ("vmxnet3: prevent building with 64K pages"), prevent the driver from building when 256K pages are enabled.
