Our home-grown buffer management needs to go away and we need
to be playing nicely with the page_pool infrastructure. This
converts the Rx traffic queues to use page_pool.
Also, since ionic_rx_buf_size() was removed, redefine
IONIC_PAGE_SIZE to account for IONIC_MAX_BUF_LEN being the
largest allowed buffer to prevent overflowing u16 variables,
which could happen when PAGE_SIZE is defined as >= 64KB.
include/linux/minmax.h:93:37: warning: conversion from 'long unsigned int' to 'u16' {aka 'short unsigned int'} changes value from '65536' to '0' [-Woverflow]

If you have a network (Ethernet) card belonging to this class, say Y.

Note that the answer to this question doesn't directly affect the

kernel: saying N will just cause the configurator to skip all

the questions about Pensando cards. If you say Y, you will be asked
