RDMA/bnxt_re: Fix the sideband buffer size handling for FW commands
bnxt_qplib_rcfw_alloc_sbuf allocates 24 bytes and it is better to fit on stack variables. This way we can avoid unwanted kmalloc call. Call dma_alloc_coherent directly instead of wrapper bnxt_qplib_rcfw_alloc_sbuf.
Also, FW expects the side buffer needs to be aligned to BNXT_QPLIB_CMDQE_UNITS(16B). So align the size to have the extra padding bytes.

RDMA/bnxt_re: consider timeout of destroy ah as success.
If destroy_ah is timed out, it is likely to be destroyed by firmware but it is taking longer time due to temporary slowness in processing the rcfw command. In worst case, there might be AH resource leak in firmware.
Sending timeout return value can dump warning message from ib_core which can be avoided if we map timeout of destroy_ah as success.

RDMA/bnxt_re: Fix the page_size used during the MR creation
Driver populates the list of pages used for Memory region wrongly when page size is more than system page size. This is causing a failure when some of the applications that creates MR with page size as 2M. Since HW can support multiple page sizes, pass the correct page size while creating the MR.
Also, driver need not adjust the number of pages when HW Queues are created with user memory. It should work with the number of dma blocks returned by ib_umem_num_dma_blocks. Fix this calculation also.

RDMA/bnxt_re: Refactor hardware queue memory allocation
At top level there are three major data structure addition. viz bnxt_qplib_hwq_attr, bnxt_qplib_sg_info and bnxt_qplib_tqm_ctx
Intorduction of first data structure reduces the arguments list to bnxt_re_alloc_init_hwq() function. There are changes all over the driver code to incorporate this new structure. The caller needs to fill the attribute data structure and pass to this function.
The second data structure is to pass memory region description viz. sghead, page_size and page_shift. There are changes all over the driver code to initialize bnxt_re_sg_info data structure. The new data structure helps to reduce the argument list of __alloc_pbl() function call.
Till now the TQM rings related members were not collected under any specific data-structure making it hard to manage. The third data sctructure bnxt_qplib_tqm_ctx is added to refactor the TQM queue allocation and initialization.

RDMA/bnxt_re: Honor vlan_id in GID entry comparison
A GID entry consists of GID, vlan, netdev and smac. Extend GID duplicate check comparisons to consider vlan_id as well to support IPv6 VLAN based link local addresses. Introduce a new structure (bnxt_qplib_gid_info) to hold gid and vlan_id information.
The issue is discussed in the following thread https://lore.kernel.org/r/AM0PR05MB4866CFEDCDF3CDA1D7D18AA5D1F20@AM0PR05MB4866.eurprd05.prod.outlook.com

RDMA: Handle AH allocations by IB/core
Simplify drivers by ensuring lifetime of ib_ah object. The changes in .create_ah() go hand in hand with relevant update in .destroy_ah().
We will use this opportunity and convert .destroy_ah() to don't fail, as it was suggested a long time ago, because there is nothing to do in case of failure during destroy.

RDMA/bnxt_re: Use correct sizing on buffers holding page DMA addresses
umem->nmap is used while allocating internal buffer for storing page DMA addresses. This causes out of bounds array access while iterating the umem DMA-mapped SGL with umem page combining as umem->nmap can be less than number of system pages in umem.
Use ib_umem_num_pages() instead of umem->nmap to size the page array. Add a new structure (bnxt_qplib_sg_info) to pass sglist, npages and nmap.
