Analyze and fix the following issue in the Linux kernel code: IPoIB/CM: Enable SRQ support on HCAs that support fewer than 16 SG entries
Problem Details: Some HCAs (such as ehca2) support SRQ, but only support fewer than 16 SG entries for SRQs. Currently IPoIB/CM implicitly assumes all HCAs will support 16 SG entries for SRQs (to handle a 64K MTU with 4K pages). This patch removes that restriction by limiting the maximum MTU in connected mode to what t...
