Swapnil Ingle 6cebe9d06b nvmf: Support physical block size if exposed by bdev ... (Note: this patch was previously applied as b32cfc46 and then reverted as 63642bef.) Today the in-guest nvme device shows physical_block_size=512 even though the backend iSCSI bdev supports physical_block_size=4K iSCSI targets exposes physical block size using logical_block_per_physical_block_exponent in READ_CAPACITY_16 NPWG is one of the way to let Linux nvme driver set physical_block_size of the nvme block device. This patch adds spdk_bdev.phys_blocklen which is updated if the iSCSI backend exposes physical_block_size. Later phys_blocklen is used in nvmf to set NPWG and NAWUPF to report back during NS identity. Linux driver uses min(nawupf, npwg) to set physical_block_size. Similarly in scsi_bdev fill lbppbe in READ_CAP16 response based on spdk_bdev.phys_blocklen.
