> Issue can be seen on platforms that use 8K and above page size
> while rds fragment size is 4K. On those platforms single page is
> shared between 2 or more rds fragments. Each fragment has its own
> offset and rds congestion map code need to take this offset to account.
> Not taking this offset to account lead to reading the data fragment
> as congestion map fragment and hang of the rds transmit due to far
> congestion map corruption.
